Analytical Study on Seismic Response Control of Multistory RC Building Frame Using Various Types of Bracing Systems

Abstract

Seismic design relies on inelastic deformation through hysteretic behavior. During severe earthquakes the structural system undergoes extensive damage that result in high cost of repair. Research these days has elevated and surpassed common human instinct. One such research that backed structural systems to sustain tremors of earthquake is metallic braces. These components are predominantly the lateral force resisting system in any building structure. The installation of braces within a structure system will magnetize substantial part of destruction while the parent elements persist elastically with inferior inelastic deformation. Dissipation of seismic energy occurs through inelastic yielding and buckling of bracing member in tension and compression respectively. In the present work structured in a reinforced concrete G+7 storied moment resisting frame building which modeled using (Software for Analysis and Design) SAP-2000. The building modeled in accordance with the provisions prescribed by IS:1893 2012 part I. Three patterns of bracing will be fabricated on the peripheral frame of erection, where pattern being X, V and Inverted V. Both types of non linear analysis i.e. dynamic time history (NTH) .Results for NTH will described in the form of storey displacement, storey drift, shear force, bending moment and energy dissipated by frame and bracing.
