SEISMIC RESPONSE OF REINFORCED CONCRETE STRUCTURE BY USING DIFFERENT BRACING SYSTEMS

Umesh.R.Biradar, Shivaraj Mangalgi

Abstract: Bracings systems are one of the lateral load resisting system which has got structural importance specially in reinforced concrete buildings. Different bracing systems are efficient enough for seismic responses. To know the importance of different bracing systems in multistorey RC frame structure. 7 models with different bracing systems have been modeled and analysed for linear static(ESA),linear dynamic(RSA) ,non linear static(Pushover Analysis) and non linear dynamic analysis(Time history Analysis) by ETABS software .Results such as fundamental time period , seicmic base shear , storey displacement and storey drift have been evaluated and compared with bare frame model. Model 2 (X bracing system) is showing better seismic performance out of all the models
