Evaluating Nonlinear Behavior of a Reinforced Concrete Building with Shear Walls and Concentric Steel Bracings
In this study, the seismic performance of buildings with shear wall and steel bracing were evaluated. To this, a nine-storey reinforced concrete (RC) building having a square plan with five bays in both directions and identical story height was considered. The building consists of typical beam-column frames. RC shear walls and concentric steel bracings were used to improve the seismic behavior of the structure. A total of five building cases were taken into account as the existing building and those upgraded with the shear wall, X-bracing, inverted-V bracing, and diagonal bracing. The nonlinear static pushover and nonlinear time history analyses were performed through ETABS Software. From these analyses, the normalized base shear versus roof drift ratio, variation of maximum displacement and inter-storey drift ratio with story level, and time history plots were obtained for each of the buildings with and without shear walls and steel bracings. It was observed that the seismic capacity of the existing RC building was noticeably enhanced with the applied wall and brace, and its performance state altered from collapse prevention to life safety.
