This thesis is basically based on the comparison of the use of voided slab, RCC Solid slab and RCC Girder. In this study analysis and cost comparison of RCC Solid slab deck, RCC Voided slab deck and RCC Girder is done for superstructure spanning 20 m length. Solid slabs having greater span are uneconomical due to heavy dead load of concrete. To make it economical longitudinal beams are provided for spans greater than 10.0 m. Reinforced Concrete Girder is generally adopted for a fly over or road bridge, but in case of a river bridge with submersible superstructure, the longitudinal beams creates obstruction to the flow of water and results in additional stresses in cross direction on beams. To reduce the self weight of concrete without sacrificing its flexural strength, in solid slab voids are incorporated in concrete section. This technic offers many advantages over a conventional solid concrete slab like reduced material use, lower total cost of construction, and increased structural efficiency. This report also shows that the dead load of bridge superstructure can be reduced by providing voids in concrete where it is unnecessarily provided. Presence of voids within the concrete structure makes analysis of structure very complicated. The analysis of RCC Solid slab, RCC Girder and RCC voided slab deck for various loads as specified in IRC is done using staad pro software for span length of 20 m and width of 15.10 m. The analysis illustrates the behavior of bending moments, Shear Force, displacements, reactions for various load conditions. It is concluded that use of voided slab is more feasible for 20 m length and 15.10 m width. It is also economical as compared to solid slab and Reinforced concrete Girder. Kunal Songra | M. C.

Beam column joints in concrete framed structure have been identified as critical member for transferring forces and bending moments between beams and columns. The change of moments in beam and columns across the joint region, under loadings, induces high shear force and stresses as compared with other adjacent members. The shear failure caused is often brittle in nature which is not an acceptable structural performance. Retrofitting enhances the moment carrying capacity of joint. Often beam column joints need to be strengthened. Author proposes use of ferrocement for retrofitting as wrapping technique, cost effective alternative to costly FRP wrapping technique. In this present research study, modelling & comparison of Beam-Column joint with and without ferrocement jacket is carried out by finite element method using software ANSYS APDL. The comparison shows enhanced performance of the jacketed model over Non jacketed in terms of stresses, ultimate load carrying capacity.

Comparitive study on rcc and composite (cft) multi storeyed buildingseSAT Journals
Abstract In India reinforced concrete structures are mostly used since this is the most convenient & economic system for low-rise buildings. However, for medium to high-rise buildings this type of structure is no longer economic because of increased dead load, less stiffness, span restriction and hazardous formwork. So the structural engineers are facing the challenge of striving for the most efficient and economical design solution. Use of composite material is of particular interest, due to its significant potential in improving the overall performance through rather modest changes in manufacturing and constructional technologies. Steel-concrete composite columns are used extensively in modern buildings. Extensive researches on composite columns in which structural steel section are encased in concrete have been carried out. In-filled composite columns, however have received limited attention compared to encased columns. In this study E-Tabs nonlinear software is used for simulation of steel concrete composite (CFT) with steel reinforced concrete structures (RCC) of G+14, G+19 and G+24 stories each are considered for comparative study. Comparison of parameters like time period, storey displacement and storey drift is done. Keywords: Composite CFT columns, bracings, shear wall, time period, storey displacement and storey drift.
Analysis of High Rise Building Connection for Square Hollow Beam and Column U...ijtsrd
Most of the steel structures in India are made of conventional steel sections such as angle, channel and beam sections . However, new hollow steel sections such as square and rectangular hollow sections are gaining popularity in recent steel constructions due to a number of advantages such as its higher strength to weight ratio, better fire resistance properties, higher radius of gyration, lesser surface area, etc. This type of hollow sections can save cost up to 30 to 50 over the conventional steel sections Tata Steel brochure, 2012 17 . But unlike the conventional steel sections these hollow sections do not have standard connection details available in design code or in published literature. To overcome this problem the objective of the present study was identified to develop a suitable and economic connection detail between two square hollow sections which should be capable of transmitting forces smoothly and easy to be fabricated. To achieve the above objective, a square hollow beam to square hollow column connection was selected and modeled in commercial finite element software ABAQUS. This model was analyzed for nonlinear static pushover analysis considering a number of connection details. Following four alternative scheme of connection details were selected for this study i using end plate, ii using angle section, iii using channel sections, and iv using collar plates. The base model rectangular hollow beam welded to one face of the rectangular hollow column is also studied for reference. The performance of the selected connection details are compared and the best performing connection details is recommended for rectangular hollow beam to rectangular hollow column joints. The result shows that the load carrying capacity of the joint and the maximum deformation capacity is highly sensitive to the type of connection used. Also, the location of formation of plastic hinges in the structure which can beat joint or at beam depends highly on the type of connection used.

Comparitive study on rcc and composite (cft) multi storeyed buildingseSAT Journals
Abstract In India reinforced concrete structures are mostly used since this is the most convenient & economic system for low-rise buildings. However, for medium to high-rise buildings this type of structure is no longer economic because of increased dead load, less stiffness, span restriction and hazardous formwork. So the structural engineers are facing the challenge of striving for the most efficient and economical design solution. Use of composite material is of particular interest, due to its significant potential in improving the overall performance through rather modest changes in manufacturing and constructional technologies. Steel-concrete composite columns are used extensively in modern buildings. Extensive researches on composite columns in which structural steel section are encased in concrete have been carried out. In-filled composite columns, however have received limited attention compared to encased columns. In this study E-Tabs nonlinear software is used for simulation of steel concrete composite (CFT) with steel reinforced concrete structures (RCC) of G+14, G+19 and G+24 stories each are considered for comparative study. Comparison of parameters like time period, storey displacement and storey drift is done. Keywords: Composite CFT columns, bracings, shear wall, time period, storey displacement and storey drift.
Analysis of High Rise Building Connection for Square Hollow Beam and Column U...ijtsrd
Most of the steel structures in India are made of conventional steel sections such as angle, channel and beam sections . However, new hollow steel sections such as square and rectangular hollow sections are gaining popularity in recent steel constructions due to a number of advantages such as its higher strength to weight ratio, better fire resistance properties, higher radius of gyration, lesser surface area, etc. This type of hollow sections can save cost up to 30 to 50 over the conventional steel sections Tata Steel brochure, 2012 17 . But unlike the conventional steel sections these hollow sections do not have standard connection details available in design code or in published literature. To overcome this problem the objective of the present study was identified to develop a suitable and economic connection detail between two square hollow sections which should be capable of transmitting forces smoothly and easy to be fabricated. To achieve the above objective, a square hollow beam to square hollow column connection was selected and modeled in commercial finite element software ABAQUS. This model was analyzed for nonlinear static pushover analysis considering a number of connection details. Following four alternative scheme of connection details were selected for this study i using end plate, ii using angle section, iii using channel sections, and iv using collar plates. The base model rectangular hollow beam welded to one face of the rectangular hollow column is also studied for reference. The performance of the selected connection details are compared and the best performing connection details is recommended for rectangular hollow beam to rectangular hollow column joints. The result shows that the load carrying capacity of the joint and the maximum deformation capacity is highly sensitive to the type of connection used. Also, the location of formation of plastic hinges in the structure which can beat joint or at beam depends highly on the type of connection used.

The Impact of Digital Media on the Decentralization of Power and the Erosion ...ijtsrd
The impact of digital media on the distribution of power and the weakening of traditional gatekeepers has gained considerable attention in recent years. The adoption of digital technologies and the internet has resulted in declining influence and power for traditional gatekeepers such as publishing houses and news organizations. Simultaneously, digital media has facilitated the emergence of new voices and players in the media industry. Digital medias impact on power decentralization and gatekeeper erosion is visible in several ways. One significant aspect is the democratization of information, which enables anyone with an internet connection to publish and share content globally, leading to citizen journalism and bypassing traditional gatekeepers. Another aspect is the disruption of conventional media industry business models, as traditional organizations struggle to adjust to the decrease in advertising revenue and the rise of digital platforms. Alternative business models, such as subscription models and crowdfunding, have become more prevalent, leading to the emergence of new players. Overall, the impact of digital media on the distribution of power and the weakening of traditional gatekeepers has brought about significant changes in the media landscape and the way information is shared. Further research is required to fully comprehend the implications of these changes and their impact on society.

The Role of Mentoring and Its Influence on the Effectiveness of the Teaching ...ijtsrd
This paper reports on a study which was conducted to investigate the role of mentoring and its influence on the effectiveness of the teaching of Physics in secondary schools in the South West Region of Cameroon. The study adopted the convergent parallel mixed methods design, focusing on respondents in secondary schools in the South West Region of Cameroon. Both quantitative and qualitative data were collected, analysed separately, and the results were compared to see if the findings confirm or disconfirm each other. The quantitative analysis found that majority of the respondents 72 of Physics teachers affirmed that they had more experienced colleagues as mentors to help build their confidence, improve their teaching, and help them improve their effectiveness and efficiency in guiding learners’ achievements. Only 28 of the respondents disagreed with these statements. With majority respondents 72 agreeing with the statements, it implies that in most secondary schools, experienced Physics teachers act as mentors to build teachers’ confidence in teaching and improving students’ learning. The interview qualitative data analysis summarized how secondary school Principals use meetings with mentors and mentees to promote mentorship in the school milieu. This has helped strengthen teachers’ classroom practices in secondary schools in the South West Region of Cameroon. With the results confirming each other, the study recommends that mentoring should focus on helping teachers employ social interactions and instructional practices feedback and clarity in teaching that have direct measurable impact on students’ learning achievements.

This study primarily focuses on the design of a high side buck converter using an Arduino microcontroller. The converter is specifically intended for use in DC DC applications, particularly in standalone solar PV systems where the PV output voltage exceeds the load or battery voltage. To evaluate the performance of the converter, simulation experiments are conducted using Proteus Software. These simulations provide insights into the input and output voltages, currents, powers, and efficiency under different state of charge SoC conditions of a 12V,70Ah rechargeable lead acid battery. Additionally, the hardware design of the converter is implemented, and practical data is collected through operation, monitoring, and recording. By comparing the simulation results with the practical results, the efficiency and performance of the designed converter are assessed. The findings indicate that while the buck converter is suitable for practical use in standalone PV systems, its efficiency is compromised due to a lower output current.

Sustainable Energy by Paul A. Adekunte | Matthew N. O. Sadiku | Janet O. Sadikuijtsrd
Energy becomes sustainable if it meets the needs of the present without compromising the ability of future generations to meet their own needs. Some of the definitions of sustainable energy include the considerations of environmental aspects such as greenhouse gas emissions, social, and economic aspects such as energy poverty. Generally far more sustainable than fossil fuel are renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy sources. Worthy of note is that some renewable energy projects, like the clearing of forests to produce biofuels, can cause severe environmental damage. The sustainability of nuclear power which is a low carbon source is highly debated because of concerns about radioactive waste, nuclear proliferation, and accidents. The switching from coal to natural gas has environmental benefits, including a lower climate impact, but could lead to delay in switching to more sustainable options. “Carbon capture and storage” can be built into power plants to remove the carbon dioxide CO2 emissions, but this technology is expensive and has rarely been implemented. Leading non renewable energy sources around the world is fossil fuels, coal, petroleum, and natural gas. Nuclear energy is usually considered another non renewable energy source, although nuclear energy itself is a renewable energy source, but the material used in nuclear power plants is not. The paper addresses the issue of sustainable energy, its attendant benefits to the future generation, and humanity in general. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.

Concepts for Sudan Survey Act Implementations Executive Regulations and Stand...ijtsrd
This paper aims to outline the executive regulations, survey standards, and specifications required for the implementation of the Sudan Survey Act, and for regulating and organizing all surveying work activities in Sudan. The act has been discussed for more than 5 years. The Land Survey Act was initiated by the Sudan Survey Authority and all official legislations were headed by the Sudan Ministry of Justice till it was issued in 2022. The paper presents conceptual guidelines to be used for the Survey Act implementation and to regulate the survey work practice, standardizing the field surveys, processing, quality control, procedures, and the processes related to survey work carried out by the stakeholders and relevant authorities in Sudan. The conceptual guidelines are meant to improve the quality and harmonization of geospatial data and to aid decision making processes as well as geospatial information systems. The established comprehensive executive regulations will govern and regulate the implementation of the Sudan Survey Geomatics Act in all surveying and mapping practices undertaken by the Sudan Survey Authority SSA and state local survey departments for public or private sector organizations. The targeted standards and specifications include the reference frame, projection, coordinate systems, and the guidelines and specifications that must be followed in the field of survey work, processes, and mapping products. In the last few decades, there has been a growing awareness of the importance of geomatics activities and measurements on the Earths surface in space and time, together with observing and mapping the changes. In such cases, data must be captured promptly, standardized, and obtained with more accuracy and specified in much detail. The paper will also highlight the current situation in Sudan, the degree to which survey standards are used, the problems encountered, and the errors that arise from not using the standards and survey specifications.

Towards the Implementation of the Sudan Interpolated Geoid Model Khartoum Sta...ijtsrd
The discussions between ellipsoid and geoid have invoked many researchers during the recent decades, especially during the GNSS technology era, which had witnessed a great deal of development but still geoid undulation requires more investigations. To figure out a solution for Sudans local geoid, this research has tried to intake the possibility of determining the geoid model by following two approaches, gravimetric and geometrical geoid model determination, by making use of GNSS leveling benchmarks at Khartoum state. The Benchmarks are well distributed in the study area, in which, the horizontal coordinates and the height above the ellipsoid have been observed by GNSS while orthometric heights were carried out using precise leveling. The Global Geopotential Model GGM represented in EGM2008 has been exploited to figure out the geoid undulation at the benchmarks in the study area. This is followed by a fitting process, that has been done to suit the geoid undulation data which has been computed using GNSS leveling data and geoid undulation inspired by the EGM2008. Two geoid surfaces were created after the fitting process to ensure that they are identical and both of them could be counted for getting the same geoid undulation with an acceptable accuracy. In this respect, statistical operation played an important role in ensuring the consistency and integrity of the model by applying cross validation techniques splitting the data into training and testing datasets for building the geoid model and testing its eligibility. The geometrical solution for geoid undulation computation has been utilized by applying straightforward equations that facilitate the calculation of the geoid undulation directly through applying statistical techniques for the GNSS leveling data of the study area to get the common equation parameters values that could be utilized to calculate geoid undulation of any position in the study area within the claimed accuracy. Both systems were checked and proved eligible to be used within the study area with acceptable accuracy which may contribute to solving the geoid undulation problem in the Khartoum area, and be further generalized to determine the geoid model over the entire country, and this could be considered in the future, for regional and continental geoid model.

DeepMask Transforming Face Mask Identification for Better Pandemic Control in...ijtsrd
The COVID 19 pandemic has highlighted the crucial need of preventive measures, with widespread use of face masks being a key method for slowing the viruss spread. This research investigates face mask identification using deep learning as a technological solution to be reducing the risk of coronavirus transmission. The proposed method uses state of the art convolutional neural networks CNNs and transfer learning to automatically recognize persons who are not wearing masks in a variety of circumstances. We discuss how this strategy improves public health and safety by providing an efficient manner of enforcing mask wearing standards. The report also discusses the obstacles, ethical concerns, and prospective applications of face mask detection systems in the ongoing fight against the pandemic.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

superstructure and the polished appearance. The
reinforced solid slabs are generally provided at
bridges with a span which are up to 15 m.
B. RCC Girder - Girder is that horizontal member
of bridge superstructure which is normally a beam
which is subjected to loading due to which
straining and shearing forces acts on the axial and
lateral cross section. In Reinforced concrete
girders the reinforced concrete combines concrete
and steel bars by simply putting them together
and letting them act together naturally. When the
loading conditions are applied on a reinforced
concrete girder it changes. Reinforced Concrete
Girder Bridge is adopted normally as a
superstructure of a bridge in the span range of 10
to 25 m. For the larger spans the dead loads
becomes too high. Because of easy geometry,
simple erection and casting T beams are very
famous and generally provided. To carry the
traffic (Vehicles and pedestrians), a reinforced
concrete slab is provided above the girders.
C. Voided Slab - Voided Slabs are a precast pre
stressed and RCC in situ slab for bridge, building,
marine pier and underpass structures. These type
of slabs can be utilized where slab depth may be a
concern or when less construction time is
required. The voided slab is being used in
construction field around 100 years. By providing
the voids in between the slab, dead load of the
slab can be reduced and this helps in reducing the
overall quantity of concrete in slab which also
helps in the reduction in cost of the slab.
D. PSC Girder- Pre stressed concrete Girder is the
most updated major type of construction
introduced in the field of bridge engineering
because of its major advantages like, the scale or
dimension of structural members are decreased,
which can enhance the clearances or reduce the
height of structures. It also allows the
construction and design of huge spans (more than
30 m) with small members, even when a heavy
weights are applied.
1.2. Objective
The main objectives of this study are:
A. To compare three different type of superstructures
i.e. RCC Solid Slab, RCC Girder and RCC
Voided slab in simply supported bridge structure.
B. To select the span length, grade of materials used
and make grillage of all three types of
superstructures with properties, supports and
loads as per IRC 6-2017.
C. To check the results and analyze all three type of
superstructures i.e. voided slab, RCC I girder and
Solid Slab.
D. To determine the difference in stresses and
moments generated in all three types of structures.
E. To determine the quantity of concrete and steel
for RCC Solid slab, RCC Girder and RCC Voided
slab in simply supported bridge structure.
F. Determination of changes and differences in cost
of all three types of superstructures.
2. Literature Review
K. Hemalatha, Chippymol James, L. Natrayan, V.
Swamynad (July 2020) analyzed pre stressed
concrete box girder bridges and RCC T Beam super
structure under various span conditions. The objective
of the study was to reduce dead load, extra usage of
material, which is not used to its full potential, is
removed from this section, which can be in the shape
of cellular structures or box girder structures
depending on whether the shear deformations are
neglected or not. After all the analysis this study
shows that the ultimate shear strength is within the
limits as per IRC 112:2011. The results of this study
concludes that for 16 m length of span, RCC Tee
beam girder bridge is safe to adopt and easy to build a
cast in-situ type of bridge. Since in the study the deck
of the bridge was casted monolithically with slab, the
flange of the girder also bears the compressive
stresses generated in it that mean it will resist the
sagging moment on deck more effectively. Further
the results concluded that, the ultimate shear strength,
minimum section modulus at service loads, stresses at
service loads and ultimate flexural strength are within
the limits as per IRC 112:2011 and IS: 1343-2012.
This study also proves that 50 m length of span, Pre
stressed Concrete Box Girder Bridge can be adopted.
Rahul Gangwar, Ankur Pratap Singh, T.N.Pandey
(April 2020) compared RCC and PSC Girder of
various spans which includes the design and estimates
of both type of structures. The motive of the study
was to study RCC as well PSC Girder of different
span and find out the difference in design and
estimation. In this study while calculating the cost of
PSC Girder cost of accessories like spilt cones,
bearing plates, sheathing duct and cost of prestressing
were also considered and after the quantity
calculations it was concluded that from spans 10 m to
18 m, PSC Girder is economical, as the span
increases its economic efficiency also increases. The
deflection in girder also decreases in the case of pre
stressed concrete which satisfies the limit state of
serviceability & durability. This study also shows the
saving of concrete quantity and reinforcement but as

there is a huge saving of material in prestressed
concrete structure but on the other hand skilled labor
and accessories are required to execute prestressed
girder. Further it was concluded that Reinforced
concrete beams are generally heavy. They always
need shear reinforcements besides the longitudinal
reinforcement for flexure. Prestressed concrete beams
are lighter. By using the curved tendons and the pre-
compression, the most part of the shear is resisted.
High strength concrete is not needed in reinforced
concrete beams. But high strength concrete and high
strength steel are very important for prestressed
concrete beams.
Situations which demands weight more than strength,
reinforced concrete beams can be used because
reinforced concrete beams are heavy and massive. For
heavy load and larger spans prestressed girders can be
used because in prestressed beams slender and artistic
treatments can be easily provided. The deflection of
prestressed beams are small so the cracks do not
occur under working loads. If in case even a minute
crack is developed, such crack gets closed when the
overload is removed.

compared after changing the simply supported
bridges into continuous bridges and then analyzed the
behavior of continuous bridges with respect to that of
simply supported bridges.
For this study six cases of simply supported were
considered. For the comparison study the simply
supported bridges, the bending moments developed in
continuous bridges were considerably very less and
therefore smaller sections can be adopted which
results in economy of steel and concrete. The ultimate
moment carrying capacity of continuous bridge deck
was higher than that of simply supported decks due to
the fact of redistribution of moments in continuous
type of structures. Results of the study shows that for
spans up to 6 m the dead load moments obtained were
63% as of live load moments and for span of 8 m
length they were approximately equal. At 12 m and
10 m spans the dead load moments calculated were
2.40 times and 1.50 times if compared to that of dead
load moments respectively. The study concluded that
from slab design point of view it is way better to
choose continuous two or three spans in multiple of 4
m, 5 m and 6 m. The study further suggested that use
of continuous spans in place of single span reduces
dead load, live load and design moments
considerably. This study observed that providing two
spans instead of one span reduces moments from 80%
to 90% and providing three spans instead of one span
reduces moments approximately 92%.
Rajesh F. Kale, N.G.Gore, P.J.Salunke (January
2014) in this study, cost optimization approach of
R.C.C. T-beam girder was discussed. The main aim
of the study was to minimize the total cost in the
design process of the bridge structure considering the
cost of materials. For a specific span of girder and
width of bridge, the design variables considered for
the minimization of cost of the bridge system, are
deck slab depth, width of web of girder and, depth of
girder, (i.e. X1, X2, X3 resp.) Design constraints for
the development are considered according to Standard
Specifications from IRC-21:2000 (Indian road
congress). The development process was done for
different grade of concrete and steel. The results for
different grade of steel and concrete were compared
was presented in tabulated form. The optimization
problem is classified by having a combination of
continuous, discrete and integer sets of design
variables. The structure was modeled and calculated
using the direct design method. Optimization problem
is formulated is in nonlinear programming problem
(NLPP) by SUMT. In this study the optimization for
reinforced concrete R.C.C. T type beam girder system
was explained and the results of the optimum and old
design procedures are compared. The results of the
study also suggests that it is possible to formulate and
to obtain solution for the minimum cost design for
R.C.C. T-beam girder, Interior penalty function
method can be used for solving resulting non-linear
optimization problems. The study showed that it is
possible to obtain the global minimum for the
optimization problem by starting from different
starting points with the interior penalty function
method. The minimum cost design of R.C.C. T-beam
girder is fully constrained design which is defined as
the design bounded by at least as many constraints as
there are the design variables in the problems. Actual
percentage of the saving obtained for optimum design
for R.C.C. T-beam girder depend upon the deck slab
thickness, depth of girder, grade of steel and grade of
concrete. The optimum cost for a R.C.C. T-beam
girder is achieved in M25 grade of concrete and fe415
grade of steel. The cost of R.C.C. T-beam girder unit
increased rapidly with respect grade of concrete
increases and grade of steel increases whereas cost of
R.C.C. T-beam girder decreases as the span of bridge
reduces, also the cost of girder decreases with the
increase in the girder depth. Noticeable savings in
cost over the normal design can be achieved by the
optimization. However the study showed that the
actual percentage.

Solid Slab, Voided slab and RCC I Girder for
earthquake zone II where we have assumed that type
of substructure is same for all three deck system,
there foundation is assumed to rest on soil having
SBC of 30 t/m2
and analysis of bridge deck is to be
done in STAAD PRO V8i software. The result is
compare on basis of quantity of concrete and steel is
used in bridge deck, depth of bridge deck, cost,
maximum stresses, maximum displacement,
maximum force, and maximum bending moment.
Here three different model is prepared for consider
three bridge deck for having a same span of 20m and
width of structure is 15.1m and load is applied as per
IRC 6-2017 where Live load is to consider for 4 lane
Class A Loading, 2 lane of Class A and One
Lane of Class 70R and also 2 Lane of Class 70 R.
3.2. Loading Combination
Various Load Considered for design of Super-
Structure which are as follows:
1. Dead Load: It includes weight of Superstructure
itself.
A. In case Solid Slab: It includes the weight of solid
Slab
B. In case of Voided Slab: It includes weight of
Voided Slab Excluding the weight of Voids.
C. In case of RCC I Girder: It includes weight of
girder, diaphragms and deck slab.
2. Super-Imposed Load: It is generally imposed
dead load on bridge deck i.e. Crash Barrier load
and Wearing Coat load.
3. Live Load: Live Load is consider as per IRC 6-
2017, as in our case we have consider width of
structure is 15.1 m, so as per IRC the above three
structure should be design vehicular load as per
follow:
A. 4 Lane For Class A Vehicle
B. 2 Lane for Class A Vehicle + 1 lane for Class 70
R
C. 2 Lane for Class 70 R
The live load cases shown above are for a 4 lane
carriage way. The live load combination decided on
basis of carriage way width of bridge which is as per
IRC 6-2017, table -6.
The shear force and bending moment for every load
case is decided at distance d from the support and at
mid of the span of a bridge. The bending obtained at
mid of span is used to calculate area of reinforcement,
hence longitudinal reinforcement is obtained. The
curtailment to be provided at distance from 0.25
effective length of span based of moment at that
section.
3.3. Methodology
The process of analysis and design of Super structure
performed on STAAD–Pro V8i in accordance with
IRC 6-2017, IRC SP 64-2016 and IRC 112-2020 is
shown through Flow Chart below.

Step -1 Modelling of Bridge Decks:
A bridge deck is assume to be beam when its length is more than its width that load act on it tends to bend and
twist along its length of cross section within the elastic limit. So in order to analyze bridge deck in computer
software in grillage analysis method is used in order to get proper result. Therefore in Grillage analysis designer
should kept in mind following points in order to develop proper grillage mesh are as follows:
1. Designer should know how the structure will behave and placing of grillage beam coincide with lines of
desired strength.
2. Designer also consider how forces will be distributed within the prototype i.e. torsion shear flow, vertical
shear flow within cross section of beam.
3. Number of Longitudinal member can be any number and should be selected throughout the width of bridge
in such a way that local dispersion with grillage mesh is neglected.
4. The spacing within transverse member should be less so that fully load is taken by longitudinal member and
should be kept less one-fourth of effective span.
5. Transverse member should be orthogonal to longitudinal member unless it is skew in nature, but in our case
it is not skew.
6. In Grillage analysis the point load represent loads distributed over the width represented by the member.
Step -2 Assigning Section Properties and support:
After preparing grillage model for each consider bridge deck slab, section properties need to assign for each
longitudinal member and transverse member in prepared Staad model for designing bridge deck. These
properties assign on basis of criteria discuss above or grillage mesh prepared, which will fit in grillage
modelling. So that bending moment, shear force develop in these member is used for designing them. The
support condition is defined for the model assuming that end bearing is Elastomeric in nature i.e. Elastomeric
Bearing hence it is defined accordingly.

Step -5 Design of structure
Separate excel sheet is prepared in design of Bridge deck which is enclose in Annexure-C, D, E. The design of
bridge deck is done as per IRC 112-2020 and IRC SP 64-2016 and section properties and area of reinforcement
required is calculated as per IRC 112-2020 and IRC SP 64-2016. General Design parameter is taken for design
as follow and mention below:
Span c/c of Expansion Joint =20m
Total Width of the Structure =15.1m
Density of concrete= 2.5 t/m2
Grade of concrete = M-35
Young Modulus of Elasticity for Concrete Ecm= 32000 MPa
Grade of main steel = Fe-500
Young Modulus of Elasticity for Concrete Es=200000 MPa
Grade of secondary steel = Fe-500
The result like Bending Moment, Shear force, Displacement etc. obtain from Staad Pro for three different bridge
deck which are Voided Slab, RCC I Girder and Solid Slab is put in excel sheet and where need to find which
type of section properties like depth of slab/girder, amount to steel is required to section is remain under-
reinforced, shear force is within permissible limit, deflection and stresses is within permissible limit in order to
satisfy serviceability criteria. As a whole just want to know structure is safe and constructible, designed is to
serve purpose for design period.

3.2.7. Maximum Bending Moment:
In case of simply supported span maximum bending moment is found to be maximum at the mid of the span of
bridge deck. For designing a bridge deck maximum bending moment is taken.

3.3. Discussion and Inferences
The analysis and designing of Bridge Deck shows the
following inferences:
1. The depth of bridge deck for RCC I girder comes
out to be more than voided slab and solid slab.
2. The quantity of concrete required for solid slab is
maximum and for RCC I Girder is minimum for
the span 20 m having a width of 15.1 m.
3. The quantity of steel required for voided slab is
maximum and for solid slab is minimum for the
span 20 m having a width of 15.1 m.
4. The cost of structure for RCC I girder is found to
be least and for the solid slab is found to be high.
5. The cost per meter for RCC I girder is also found
to be minimum. Hence we can say that for
constructing 20 m span among these bridge deck,
RCC I girder will be economical.
6. The maximum deflection and total deflection is
found to be more for voided slab and hence it can
be say that voided slab is a bridge deck which is
least satisfying the serviceability criteria.
7. The maximum force is found to be maximum for
RCC I girder and followed by solid slab and least

for voided slab for same span of the bridge having
same width of the structure.
8. The maximum bending moment is also found to
be most for RCC I girder and followed by Solid
slab and least for voided slab for same span of the
bridge having same width of the structure.
4. Conclusion
1. Considering all the above inference made on
analysis and designing of all bridge deck, we
finally conclude that the RCC I girder is most
economical bridge deck for 20 m span having a
width of 15.1 m width of structure.
2. In RCC I Girder it is also seen in from the study
that maximum displacement comes out to be
lowest and maximum shear force and maximum
bending moment comes out to be highest.
3. The quantity of concrete is found to be lowest
among rest of other bridge deck and quantity of
steel is found to be second lowest among rest of
other bridge deck but at last overall economy of
bridge is seen, it found that total cost and cost per
running meter is lowest for RCC I Girder.
