Looking to the past records of earthquakes, theres expansion inside the interest of quake opposing structures which may be fulfilled by giving the shear wall frameworks inside the structure. Furthermore inferable from the principal quakes inside the new taps the codal arrangements updated and executing extra weight age on seismic tremor style of construction. Typically shear divider will be illustrated as the underlying vertical part that is prepared to oppose a blend of shear, second and hub load iatrogenic by parallel burden and gravity load move to the wall from various help. This research work centers on the correlation of seismic investigation of private structures utilizing supporting and shear walls. The investigation of the building is conveyed in each of the four seismic which are Zone III and Zone IV. This investigation contains understanding the key parts responsible for the construction to perform severely during a seismic tremor, with the goal that they acquire their reasonable attributes for the further quakes. Demonstrating of the design will be done through STAAD professionals. V8i programming. Times pan of the design in bidirectional is reestablished from the programming itself just according to IS 1893 part 1 2002 

Shear walls are specially designed structural members provided in the multi storey buildings to resist lateral forces. These walls have very high in plane strength and stiffness, which can resist large horizontal forces and can support gravity loads. There are lots of literatures available to design and analyse the shear wall. However, what is the optimum location of shear wall in multi storey buildings are not discussed extensively in any literature. It is very necessary to determine effective, efficient and ideal location of shear wall to get effective performance of the buildings. In this paper, therefore, main focus is to determine the efficient and effective location of shear walls in multi storey buildings. In this paper, various models of G 10 storeyed building have been analysed by changing locations of shear walls for determining parameters like Base Shear, Lateral Displacement and Storey Drift. In this paper the Linear static method of analysis has been carried out on type II soil Medium soil sites for a regular structure in plan in zone V for all the frame models and various load combinations are applied using software ETABS.The presence of shear wall can affect the seismic behaviour of frame structure to large extent, and the shear wall increases the strength and lateral stiffness of the structure. It has been found that the model M 09 having shear walls at the centroid of the building in cross shape shape shows better location of shear wall. 

Among all the natural disasters such as flood, earthquake, drought, hurricanes the least understood and the most destructive one is earthquake. Since, they cause many of injuries and economical losses leaving behind a series of signs of panic. Necessity to implement seismic codes in building design. For this a better method of analysis such as static analysis, dynamic analysis and time history analysis has to be adopted for performing the structures seismic risk assessment. This dissertation work is concerned with the ""Studies on Effect of Friction Dampers on the Seismic Performance of RC G 15 Storey Buildings"" According to IS 1893 part 1 2002 codal provisions the structures are analyzed by Equivalent Static method and Time History method. The modeling and analysis is done with ETAB SOFTWARE and the results obtained are seismic parameters such as Time period, Base shear, Lateral displacement and Inter storey drift, storey stiffness, storey accelaration are tabulated and then comparative study of structures with and without Friction dampers has been done. 

Construction of building requires proper planning and management. Building are subjected to various loads such as dead load, live load ,wind load and seismic load .seismic load has extreme adverse effect on building so it is necessary to perform seismic analysis. This paper describe about the response of building when it is subjected to seismic load , this response can be shown by story drift and base shear .seismic analysis has been performed on (G+8) building which is located in zone 2 & 4 using STAAD Pro software . Analysis has been performed according to IS 1893 PART 1 (2002).

In civil structure static analysis is perform for R.C.C frame regular and irregular building upto G+15 storey by using 'œResponse Spectrum Method'. The problems introduced due to discontinuity in stiffness, mass and geometry of structure.IS codes are used for design of various civil engineering structures and their specification. These elements are designed by using software ETABS. And consider seismic load and wind load. For load combination use code IS 1893:2002. Irregular building is compared in all four zones. The designing has been carried out in ETABS software (software that deals with analysing and designing of structures. This software is easy to understand for user). All the building structure and modelled analysed and then designed for all four zones. All model are analysis in ETABS software and design in RCDC software and their results are obtained in all seismic zones. The base shear force, volume of concrete, weight of steel and cost effectiveness have been calculated to depict all the differences in structure behaviour when analysed and design in all four zones by using ETABS and RCDC software.
