EFFECT OF CONCENTRIC AND ECCENTRIC TYPE OF BRACINGS ON PERFORMANCE BASED SEISMIC ANALYSIS OF RC BUILDING

Abstract

When a tall building is subjected to lateral or torsional deflections under the action of seismicloads, the resulting oscillatory movement can induce a wide range of responses in the building's occupants.[1]As a result, lateral stiffness is a major consideration in the design of tall buildings. Bracing is a highly efficient and economical method of resisting lateral forces in a frame structure. In this present study, the effect of four different types of bracing systems have been studied, for the use in SMRF RC framed building situated in seismic zone IV, in order to provide lateral stiffness and results in terms of storey shears and storey drifts have been presented.
