Structural design is the primary aspect of civil engineering. The foremost basic in
structural engineering is the design of simple basic components and members of a building viz., Slabs,
Beams, Columns and Footings. In order to design them, it is important to first obtain the plan of the
particular building. Thereby depending on the suitability; plan layout of beams and the position of
columns are fixed.
Pushover is a static-nonlinear analysis method where a structure is subjected to gravity loading and a monotonic displacement-controlled lateral load pattern which continuously increases through elastic and inelastic behavior until an ultimate condition is reached. Lateral load may represent the range of base shear induced by earthquake loading, and its configuration may be proportional to the distribution of mass along building height, mode shapes, or another practical means.
The static pushover analysis is becoming a popular tool for seismic performance evaluation of existing and new structures. The expectation is that the pushover analysis will provide adequate information on seismic demands imposed by the design ground motion on the structural system and its components. The purpose of the paper is to summarize the basic concepts on which the pushover analysis can be based, assess the accuracy of pushover predictions, identify conditions under which the pushover will provide adequate information and, perhaps more importantly, identify cases in which the pushover predictions will be inadequate or even misleading.

The Pushover Analysis from basics - Rahul LeslieRahul Leslie
Pushover analysis has been in the academic-research arena for quite long. The papers published in this field usually deals mostly with proposed improvements to the approach, expecting the reader to know the basics of the topic... while the common structural design practitioner, not knowing the basics, is left out from participating in those discussions. Here I’m making an effort to bridge that gap by explaining the Pushover analysis, from basics, in its simplicity.

Seismic Retrofitting of a RC Building by Adding Steel Plate Shear WallsIOSR Journals
This paper deals with the step-by-step retrofitting of buildings by using steel plate shear walls
(SPSWs) with the aid of SAP2000 programme. One type of reinforced concrete building is selected for
evaluation. This building represents the most used forms of residential buildings in the Sudan, in terms of
geometric form, and dimensions. This paper uses the equivalent static method provided in the regulations
proposed by the Egyptian Society for Earthquake Engineering. One typical model was selected from the existing
residual buildings in Khartoum city, as a case study. The proposed methodology that has been used to evaluate
the seismic resistance of chosen building is done through the design of the structural elements of the buildings
before and after adding the seismic forces. The retrofitting of building was done by using steel plate shear walls
with thicknesses of 5mm, 7mm and 10mm. From the results obtained, it was found that the use of two additional
SPSWs with 7 mm thickness placed at the internal frame of the existing system, resulted in a reduction of
bending moments in the columns and beams. The increase of thickness has a clear effect on the bending moment
of the columns, but has little effects on the bending moments of the beams.
Analysis and Optimum Design for Steel Moment Resisting Frames to Seismic Exci...IJCMESJOURNAL
The essential purpose of this wander is to develop an Interior Penalty Function (IPF) based estimation to multi-storey steel traces for slightest weight of frames. The frames are proposed for contradicting even impact in view of seismic stacking close by gravity forces. Various structural stems are used for restricting seismic (lateral) forces; however steel moment resisting frames (MRFs) are considered for the present work. The framework solidifies codal courses of action of IS 800-2007, as needs be gets the edges with perfect weight for in-plane moments with lateral support of beam element. Strength and buckling criteria are considered as direct goals close by side constraints in formulating optimization problem. A Software program is made that uses an interior penalty function (IPF) for weight minimization of two-dimensional moment restricting steel encompassed structures. The program uses MATLAB, performs one dimensional interest, and structural design in an iterative technique. The design cases have exhibited that the proposed estimation gives a beneficial instrument to the practicing fundamental algorithm. The program is associated with 6 and 9 storey (4 bays) moment resisting frames (MRFs). The program showed its capacity of optimizing the largeness of two medium size frames. To get part obliges in frames an examination technique must be associated. In the present work Equivalent Lateral Force framework (ELF) and material nonlinear time history analysis (NTH) are associated and perfect qualities gained from both the examinations are contemplated.

Analysis and Design of Rectangular and L-Shaped Columns Subjected to Axial Lo...Nitin Dahiya
Next to rectangular and circular columns, L-shaped columns may be the most frequently encountered reinforced concrete columns, since they can be used as a corner column in framed structures. The behaviour of irregular shaped reinforced concrete columns has been a constant concern for a structural engineer, to design a safe and economic structure in modern buildings and bridge piers. L-shaped reinforced concrete column subjected to biaxial bending and axial compression is a common design problem. Axial load capacity and Moment capacity of rectangular and L-shaped reinforced concrete columns have been done in this work. A computer program has been developed to obtain the axial load capacity and moment capacity of reinforced concrete columns of rectangular and L-shaped.
Seismic Capacity Comparisons of Reinforced Concrete Buildings Between Standar...drboon
Earthquakes are cause of serious damage through the building. Therefore, moment resistant frame buildings are widely used as lateral resisting system. Generally three types of moment resisting frames are designed namely Special ductile frames (SDF), Intermediate ductile frames (IDF) and Gravity load designed (GLD) frames, each of which has a certain level of ductility. Comparative studies on the seismic performance of three different ductility of building are performed in this study. The analytical models are considered about failure mode of column (i.e. shear failure, flexural to shear failure and flexural failure); beam-column joint connection, infill wall and flexural foundation. Concepts of incremental dynamic analysis are practiced to assess the required data for performance based evaluations. This study found that the lateral load capacity of GLD, IDF, and SDF building was 19.25, 27.87, and 25.92 %W respectively. The average response spectrum at the collapse state for GLD, IDF, and SDF are 0.75 g, 1.19 g, and 1.33 g, respectively. The results show that SDF is more ductile than IDF and the initial strength of SDF is close to IDF. The results indicate that all of frames are able to resistant a design earthquake.
seismic response of multi storey building equipped with steel bracingINFOGAIN PUBLICATION
Steel bracing has proven to be one of the most effective systems in resisting lateral loads. Although its use to upgrade the lateral load capacity of existing Reinforced Concrete (RC) frames has been the subject of numerous studies, guidelines for its use in newly constructed RC frames still need to be developed. In this paper the study reveals that seismic performance of moment resisting RC frames with different patterns of bracing system. The three different types of bracings were used i.e. X - bracing system, V - bracing system and Inverted V - bracing system. This arrangement helped in reducing the structural response (i.e. displacement, interstorey drift, Shear Forces & Bending Moments) of the designed building structure. An (G+6) storey building was modelled and designed as per the code provisions of IS-1893:2002. And linear analysis is been carried out in the global X direction. The analysis was conducted with a view of accessing the seismic elastic performance of the building structure.
Multistoried buildings should be designed such that they offer sufficient stiffness against
lateral displacement and should have the strength to resist inertial forces imposed by the ground
motion arising from earth quakes. Seismic forces in buildings are greatest at the base of the building.
Hence one of the key factors to be considered in designing seismic resistant buildings is the base
shear. Base shear is an estimate of the maximum expected lateral force that will occur due to seismic
ground motion at the base of a structure. In this manuscript we perform a detailed study of the values
of base shear for bare frame as well as infilled frame multi bay, multistoried structures using Free
Vibration analysis in SAP 2000 as well as pseudostatic analysis presented in I.S. 1893(Part I)-2002

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

11. There are two methods to determine the earthquake
forces in the building
a. Seismic Coefficient Method or Static Method
b. Response Spectrum Method or Modal Analysis
Method
We have chosen the Seismic Coefficient Method to
determine the horizontal seismic force
12. BASE SHEAR CALCULATION
According to IS 1893 (Part 1): 2002 Clause 6.4.2 the
design horizontal seismic coefficient Ah for a structure
shall be determined by the following expression:
Ah =
Z∗I∗Sa
2∗R∗g
where,
Ah= Design horizontal acceleration spectrum value
Z = Zone factor
I = Importance factor
R = Response reduction factor
Sa/g = Average response acceleration coefficient
13. From IS 1893 (Part 1): 2002, Clause 6.4.2,
Table 2, under seismic zone v, seismic intensity “very severe”, zone factor
(Z) = 0.36
Table 6, under structure of “all other buildings”, importance factor (I)
=1.5
Table 7, under lateral load resisting system of “special RC moment-
resisting frame (SMRF)”, response reduction factor (R) = 5
h = 22.55 m
Here, approximate Tx, y = 0.075
Sa/g (x,y) = 1.90
(Ah)x,y = 0.1026
Seismic Weight of building,W =40885.97584 KN
Base Shear =(Vb)x,y = (Ah)x,y * W
= 4194.901 KN

It is necessary to provide a continuous footing under all the columns and walls
if the loads transmitted by the columns in a structure are so heavy or the
allowable soil bearing pressure small. Such a footing is called a raft or Mat

43. CONCLUSION
1. This project report is the final result of continuous effort of the project members and
more importantly in valuable guidance of our project advisor, without whose support and
guidance, this report wouldn’t have been presented.
2.During our entire work, we were able to deal with various codes for the seismic design
and analysis of composite loads, column loads, moments, deflections, nature of impacts on
each and every members of the section through ETABS analysis.
The performance of the structure during an earthquake depends largely on the arrangement
and placing of the rebars .
3.The concrete composition also plays a great role in the use and composition of rebar and
contributes on the economic use of rebar.
