Seismic Performance Evaluation of Multistory Reinforced Cement Concrete (RCC) Buildings with Different Bracing Systems Using ETABS
Abstract: Rapid urbanization has resulted in the construction of increasingly taller reinforced cement concrete (RCC) buildings in regions susceptible to earthquakes. The lateral forces generated during seismic events significantly influence the structural safety, serviceability, and overall performance of these buildings. Bracing systems have emerged as an effective technique for enhancing the lateral stiffness, reducing inter-storey drift, and improving the seismic resistance of multistory structures. This research investigates the seismic behavior of a G+14 RCC building provided with different concentric steel bracing configurations, namely X-bracing, V-bracing (Chevron), Inverted V-bracing, and Diagonal bracing. The analytical model is developed using ETABS software and analyzed according to the provisions of IS 1893 (Part 1):2016 and IS 456:2000. Linear dynamic analysis is carried out to evaluate important response parameters such as storey displacement, storey drift, base shear, natural time period, overturning moment, and column forces. Comparative evaluation of the various bracing arrangements is performed to determine the most effective configuration for improving seismic performance. The study indicates that introducing bracing systems considerably enhances the lateral stiffness of RCC buildings while reducing displacement and drift. Among the investigated configurations, X-bracing demonstrates the highest efficiency in controlling lateral deformation without significantly increasing structural weight.
