Dynamic Analysis of Multi-Storey Building for Minimization of Lateral Displacement due to Earthquake using Shear Wall

Shear walls are one of the most commonly used elements in Multi-Storeybuildings to resist the lateral loads due to earthquakes. In this paper, a multistorey building (with and without shear walls) is modeled and analyzed using STAAD-Pro. The prototype models are also tested on a shake table in the structural dynamics lab. The results of STAAD-Pro and Shake tables are compared. The main focus of the study is to investigate the seismic behavior of shear walls in multi-storey buildings and the applicabilty of the STAAD-Pro simulation to multi-storey buildings with shear walls. The modelling was done as per the Indian Standard Code IS 1893:2002, criteria for earthquake resistant design of structures part 1 general provisions and buildings. The materials used for modelling the building conforms to Indian Standard codes IS456:2000 and IS875:1987. The displacements and storey drifts computed using STAAD-Pro and shake table laboratory testing are compared. It has been found that there is complete agreement of the results. It is therefore concluded that the STAAD-Pro analysis can be used to analysed multi-stored buildings.
