STUDY OF LATERAL LOAD RESISTING SYSTEMS OF VARIABLE HEIGHTS IN ALL SOIL TYPES OF HIGH SEISMIC ZONE

Abstract

From the ancient time we know earthquake is a disaster causing event. Recent days structures are becoming more and more slender and more susceptible to sway and hence dangerous in the earthquake. Researchers and engineers have worked out in the past to make the structures as earthquake resistant. After many practical studies it has shown that use of lateral load resisting systems in the building configuration has tremendously improved the performance of the structure in earthquake. In present research we have used square grid of 20m in each direction of 5m bay in each direction, software used is ETABS 9.7.0, the work has been carried out for the different cases using shear wall and bracings for the different heights, maximum height considered for the present study is 75m. The modeling is done to examine the effect of different cases along with different heights on seismic parameters like base shear, lateral displacements and lateral drifts. The study has been carried out for the Zone V and all types of soils as specified in IS 1893-2002.
