STUDY ON EFFECT OF STOREY HEIGHT ON THE SEISMIC PERFORMANCE OF TALL BRACED BUILDINGS

A.Mallika

Abstract: Present trend of high-rise buildings in the urban scenario, there is necessity for finding effective and efficient forms of bracing systems to be used in high rise buildings to resist lateral loads.Various bracing patterns perform differently under different storey heights.The present study aims at finding the effect of storey height on the structural responses of tall braced buildings.Response spectrum analysis is performed to investigate the structural responses like lateral displacements, storey shears, storey drifts and Overturning moments.The bracing patterns studied in the present paper are diagonal, X, V and inverted V-bracings. 10-storeyed building with 3.0 m, 3.6 m and 4.2 m storeyheights is considered in zone V for the present study. In the present paper, ETABS software is used for investigating the structural responses of Tall Buildings.
