A bridge is a structure built to span a valley, road, body of water, or other physical obstacle, for the purpose of providing passage over the obstacle. Nowadays suspension bridges are the pioneers in bridge technology. Of all the bridge types in use today, the suspension bridge allows for the longest span ranging from 2,000 to 7,000 feet. This type of bridge has cables suspended between towers and the cables support vertical suspender cables that carry the weight of the deck below. This arrangement allows the deck to be level or to arc upward for additional clearance. They are ideal for covering busy waterways. In this paper limitation, assumption analysis, how it can be constructing and loads acting on the bridge is described.

This is the last lecture on the Long Span Bridges (LSB) course at Surrey University,UK. It looks at some of the LSB currently under construction around the world (Spring 2015).
Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. This module explains the types of bridges and their design characteristics.
Analyze and design of suspension bridge using sap2000vivatechijri
Structural design requires a full understanding and knowledge of all the components comprising the structure. A suspension bridge is a type of bridge in which the deck (the load-bearing portion) is hung below suspension cables on vertical suspenders. The design of modern suspension bridges allows them to cover longer distances than other types of bridges. The main element of a cable suspended bridge is the cable system. Bridges are normally designed for dead load, live load and other occasional loads. All loading and unloading conditions in analysis and design are provided as per IRC codal specifications. The whole modeling of the suspension parts of the bridge was done by using SAP2000. Suspension cable bridge having 1km span with single lane road, the intensity of road is given has 20 numbers of vehicles each loaded with 350KN (heavy loading class A-A track load) is analyzed by SAP2000. The output of the software presents results including moments, axial loads, shear force and displacements. Moreover, moments and axial load at each node and at any point within the element can be easily obtained from the software output. This thesis examines issues analysis and design calculation in over a structure will safe under all conditions.

This presentation
Everyone knows what bridges is, particularly for the engineer. A civil engineer can design a bridge that used to cross from point A to point B etc. Below is the history of bridges.
Bridge is not a construction but it is a concept, the concept of crossing over large spans of land or huge masses of water, and to connect two far-off points, eventually reducing the distance between them. The bridge provides passage over the obstacle of small caverns, a valley, road, body of water, or other physical obstacle. Designs of bridges vary depending on the nature of the terrain and the function of the bridge and where it is constructed.
The Oxford English Dictionary traces the origin of the word bridge to an Old English word brycg, of the same meaning, derived from German root brugj?.

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.

Comparative Analysis of Total Corporate Disclosure of Selected IT Companies o...ijtsrd
Disclosure is a process through which a business enterprise communicates with external parties. A corporate disclosure is communication of financial and non financial information of the activities of a business enterprise to the interested entities. Corporate disclosure is done through publishing annual reports. So corporate disclosure through annual reports plays a vital role in the life of all the companies and provides valuable information to investors. The basic objectives of corporate disclosure is to give a true and fair view of companies to the parties related either directly or indirectly like owner, government, creditors, shareholders etc. in the companies act, provisions have been made about mandatory and voluntary disclosure. The IT sector in India is rapidly growing, the trend to invest in the IT sector is rising and employment opportunities in IT sectors are also increasing. Therefore the IT sector is expected to have fair, full and adequate disclosure of all information. Unfair and incomplete disclosure may adversely affect the entire economy. A research study on disclosure practices of IT companies could play an important role in this regard. Hence, the present research study has been done to study and review comparative analysis of total corporate disclosure of selected IT companies of India and to put forward overall findings and suggestions with a view to increase disclosure score of these companies. The researcher hopes that the present research study will be helpful to all selected Companies for improving level of corporate disclosure through annual reports as well as the government, creditors, investors, all business organizations and upcoming researcher for comparative analyses of level of corporate disclosure with special reference to selected IT companies.

“One Language sets you in a corridor for life. Two languages open every door along the way” Frank Smith English as a foreign language or as a second language has been ruling in India since the period of Lord Macaulay. But the question is how much we teach or learn English properly in our culture. Is there any scope to use English as a language rather than a subject How much we learn or teach English without any interference of mother language specially in the classroom teaching learning scenario in West Bengal By considering all these issues the researcher has attempted in this article to focus on the effective teaching learning process comparing to other traditional strategies in the field of English curriculum at the secondary level to investigate whether they fulfill the present teaching learning requirements or not by examining the validity of the present curriculum of English. The purpose of this study is to focus on the effectiveness of the systematic, scientific, sequential and logical transaction of the course between the teachers and the learners in the perspective of the 5Es programme that is engage, explore, explain, extend and evaluate.

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.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

A Strategic Approach: GenAI in EducationPeter 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.

II. HISTORY OF SUSPENSION BRIDGE
Suspension bridges date back to antiquity. However, they
were not products of western technology. Their origin
appears to have been in China and the South Americas.
Travellers and explorers from Europe saw those structures
and their reports engendered interest in the suspension
principle.
The earliest metal suspension bridges were built in China.
Those bridges used iron chains suspended fromgroundlevel
over gorges or rivers. The decks consisted of wooden planks
placed directly on the chains. At least one of those bridges,
built in the sixteenth centuryis still in service.
The suspension bridgesobservedintheSouthAmericaswere
non-metallic, fibre structures used for pedestrians. Those
structures were reported in the West in the mid-eighteenth
century. The suspension principle was first applied in the
westfor temporary military bridges.
The first American suspension bridge, also a chain structure,
was built by James Finley in 1801.
Finley patented the design and later built many small
suspension bridges in Pennsylvania during the early 1800's.
Among the many novel features of Finley's design were the
use ofa simple stiffening systemfor the deck andanintuitive,
yetamazingly effective, method fordeterminingthesagofthe
chains.
The first of those was Brown's Union Bridge, completed in
1823. Thomas Telford's Menai Strait Bridge, an eyebar chain
structure, was the most important Civil Engineering feat of
the first 50 years of the nineteenth century. The bridge,
completed in 1826, had a 576-foot main span. That structure
aroused worldwide interest that led to widespread
employment of the suspension principle.
Overseas construction of classic suspension bridges has
centred in Great Britain with the Forth Road Bridge (1964),
Severn Bridge (1966), and the Humber Bridge (1980). The
Japanese erected a series of cable- stayed and suspension
bridges, includinga 2,336-foot main-spansuspensionbridge
between Honshu and Kyushu in 1973. A suspension bridge
witha 4,635- foot mainspanis being planned forHong Kong,
though the construction has been temporarily deferred. The
longest proposed suspension bridge will be the 10,82 7-foot
main-span Messina Strait Bridge between Italy and Sicily.
On the European continent, the German revival of cable-
stayed bridges has led to widespread employment of that
type of bridge.
The first cable-stayed vehicular bridge built in the US was
erected in Sitka Harbor, Alaska, in 1972. A 1,222-foot main-
span cable-stayed highway bridge is presently being built at
Luling, Louisana . That type of cable bridge has economic
advantages over most other bridge types in spans ranging
from 1,000 to 1,500 feet (10).
III. TYPES OF SUSPENSION BRIDGE
A suspension bridge is the types of bridge, which is mainly
concered with the application of tension than compression.
This bridge are usually suspendedbythemaincablesthatare
anchored with the tower at both ends of the bridge. Earlier,
tower were not provided in suspension bridgesbecausethey
were usually constructed for short spans. But nowdays,
among all the longest bridge of the world 14 bridges are
suspension bridges. Therearethanmanytypesofsuspension
bridge that exist today, described below:
Simple suspension bridge:
It is oldest typesof suspension bridge, usually constructedas
the foot bridge. In this type of bridge, a flexible deck is
provided which is supported by the cables & anchored to the
earth.
Under spanned suspension bridge:
In this types of suspension bridge the main cables are
provided below the deck.tje cables are anchored to the
ground similarly as the above type. Few numbers of
suspension bridge have been constructed like this due to
instability of the deck.
Stressed ribbon bridge:
It is the modified from the simple suspensionbridgeinwhich
deck lies on the main cables but it is stiff but not flexible.
Suspended – deck suspension bridge:
In this type of suspension bridge, the stiffed deck is attached
to the main cables with the help of suspenders. this type is
suitable for heavy traffic and lightrail.
Above are most common types of suspension bridge. Some
types of suspension bridge are hybrid type. This types of
suspension bridges have some portion of deck similar to
under - spanned suspension bridge.
IV. ASSUMPTIONS FOR ANALYSIS
An attempt to analyze a suspension bridge and account
accurately for all aspects of behavior of all the components
and materials, evenif their sizes and properties were known,
would be virtually impossible. Simplifying assumptions are
necessary to reduce the problem to a viable size. Although a
wide variety of assumptions is viable, some more valid than
others, the ones adopting in forming a particular model will
depend on the arrangement of the structure, its anticipated
mode of behavior, and thetypeofanalysis.Themostcommon
assumptions are as follows:
Materials
The materials of the structures and the structural
components are linearly elastic. This assumption allows the
superposition of actionsanddeflectionsand,hence,theuseof
linear methods of analysis. The development of linear
methodsand their solution by computer hasmadeitpossible
to analyze the large complex statically indeterminate
structures.

@ IJTSRD | Unique Paper ID – IJTSRD30517 | Volume – 4 | Issue – 3 | March-April 2020 Page 442
Participating Components:
Only the primary structural components participate in the
overall behavior. The effect of secondary structural
components and non structural components are assumed to
be negligible and conservative. Although this assumption is
generally valid, exception occurs.
• The Deck
The decks are assumed to be rigid in plane. This assumption
causes the horizontal plan displacements of all vertical
elements at a floor level to be definable in terms of the
horizontal plane rigid body rotation and translation of the
floor slab. Thus the number of unknown displacements to be
determined in the analysis is greatly reduced.
• Negligible Stiffness
Component stiffness of relatively small magnitude are
assumed negligible. These often include, for example, the
transverse bending stiffness of slabs, the minor axis stiffness
cable etc. The use of thisassumption should be dependenton
the role of the component in the structures behaviour.
• Negligible Deformations
Deformations, that are relatively small andoflittleinfluence,
are neglected. These include the shear and axial
deformations of girder, in plane bending and shear
deformation of floor slabs, and the axial deformations of
tower.
V. TYPICAL MORDEN SUSPENSION BRIDGE
The upper portion ofeach tower consisted ofa massive buttressed Gothic arch connecting two vertical legs. The legs have a tee
cross section and were spaced 30 feet apart to accommodate the trussand roadway. The inward cant ofthe cables,betweenthe
towers was intended by Roebling to confer compressive forces on the struts, giving the tower arches additional strength. The
towers rise 75 feet above the road.
The height of the towers from the river bed to the tower peaks was 242 feet. ·Each tower had an internal well, 20 by 30 feet in
cross section, under the roadway. At the top of the upper masonry courses, cast-iron bearing plates 11 by 8 feet were beddedto
support the original cables. Each cable rested ontwo large cast-iron saddles. Each saddle rested on32rollers,whichbearonthe
plates. When a second pair ofmain cables was added to the bridge in 1898, similar assemblies were encased in turrets atop the
towers. The roller assemblies for the new cables rest on massive steel girder tables mounted over the original bearing plates.
The cables were connected to land by gravity anchorages, located at the ends of the cable-supported spans. The end of each
original cable was enclosed in an anchor block, 75 feet long by 12 feet wide by 25 feet high. A 25-foot wide roadway separated
each pair of anchor houses. The original cables entered the anchor blocks on 36-foot centers. Each cable was separated into
seven strands at splay saddles located on the faces of the anchorages. In the anchor chambers, the strands were individually
looped about anchor shoes. The shoes were connected to wrought-iron eye bars by two long pins.

VI. HOW SUSPENSION BRIDGE IS MADE
The suspension bridge construction is done in a sequential
way:
First the towers (which anchor the main cables), then
main cables and lastly deck of the bridge are made. The
construction may take few months, a year or decades to
complete depending on the project.
If towers are placed in water then caissons (a concrete
or steel cylinder acts as a circular dam)are used to
remove water and provides water proof place for the
excavation of the foundation.
After the excavation, the concrete tower foundation is
constructed. When the foundation is laid, the towers
consisting of single ormultiplecolumns,madeupofhigh
strength reinforced concrete, steel orstones, are raised.
Later then anchorages are built that provide security to
the ends of thecables.
When the anchorages are completed, the main cables
are stretched between the towers and are fixed at the
ends in the anchorages. The cable is made up of twisted
steel wires having high tensile strength. Then the
suspenders (that connect deck to the main cables) are
attached to the main cables.
After the attachment of suspenders, the deck
construction is started. The deck construction must
proceed equally in both directions in order to balance
the load conditions in towers all the time. When deck is
completed, it is covered with base layer and then paved.
VII. LOADS ON SUSPENSION BRIDGE
Horizontal Tension
Taking the moments about point A taken at mid-span and
assuming that the supports are at equivalent heights, one
can solve for the horizontal tension in the cable per the
ࢃࢉ ࡸ
ࢀࢎ =
ૡࢎ
Where:
Wc = distributed load
Th = horizontal tension
L = span in meters
h = cable sag, in meters
Given the horizontal tension in the cable, solve for the slope
of the cable at the towers to acquire the maximum cable
tension at the height of the towers. Theslopeofthecable,the
corresponding total tension in all cables and the tension in
each cable may be calculated from the following
relationships:
∅ = ܖ܉ܜ−
ࢎ
;
ࡸ
ࢀ′′′′ =
ࢀࢎ
;
ܛܗ܋ ∅
ࢀ′′′′
ࢀࢉ =
ࡺ
;
Where:
ø = cable deflection angle
T’ = cable tension, in kN
N = number of cables
Tc = allowable tension per cable
One must chose the number of cables based on the
availability of cable and its respective breaking strength.
Although each cable supplier must verify the breaking
strengths of the cable, Appendix 3 may be used for academic
purposes. The sum of the walkway and handrail cable design
strengths must exceed the tension in the cable after
accounting for allowable stress design factors. Each cable
takes a load proportional to its’ cross sectional area and thus
if cables of differing sizes are used, each cable will take a
proportional load to its cross-sectional area ratio. In
accordance with AASHTO (2003) standards, the following
design approachand assumptionswereusedthroughoutthis
report. To illustrate the design process, a 31 design example
has been included through the text. By outlining pertinent
assumptions and processes, modifications to the standard
design may be used. One such scenario is a community’s
request to widen the decking from 1.0 meter width to 1.5
meters to allow for animal-pulled carts ora decreaseindeck-
width for low traffic crossings.
Pedestrian load on bridge
To find the tension in the cable, the load on the cable must be
computed. The following details the recommended design
approach per American Association of State Highway and
Transportation Officials article 3.16 and the supplemental
“Guide Specifications for Design of Pedestrian Bridges”
document. It is recommended that the reader reference
applicable codes and specifications in area of intended
construction prior to design.
Live loads
A live load of 85 pounds per square foot is designated unless
the walkway area is greater than 400 square feet. Then the
live load figure is slowly reduced between 400 square feet
and 850 square feet, at which time the minimum standard of
65 pounds per square foot isused. The 65 pounds per square
foot minimum load limit is used to provide a measure of
strength consistency with the LRFD specifications, which
specify 85 pounds per squarefoot less a load factorindicated
in the LRFD Design specification. The formula is as follows:
ܮܮܮܮܮܮܮܮ=85(0.25+15/√ܣܣܣܣ) 32
Where A is the total square feet of walkway surface area.
Therefore, using a 1.0 - meter walkway cross sectional area,
the following live load schedule would apply:

Live load schedule 1.0 m deck slab width
Furthermore, the likely case of small motor-vehicles and
animal-driven carts would require both distributed and
point- load analysis to find maximum loading case. As such,
the conservative assumption loading of 4.07 kN/m² (85
lb/ft²) is recommended.
Total LL = 4.07 kN/m,
(Assuming 1.0 meter width)
