  • Abstract:
  • Steel bracing systems provide an effective means of enhancing the seismic performance of reinforced concrete buildings by improving lateral stiffness and strength, thereby minimizing lateral displacements and mitigating potential earthquake-induced damage. Structures with plan irregularities are particularly vulnerable to seismic forces due to non-uniform mass and stiffness distribution. In this study, the seismic performance of a G+10 plan-irregular RC building located in Seismic Zone IV was analyzed using ETABS software. A total of six analytical models were developed, consisting of one unbraced frame and five braced frames employing different steel bracing configurations—X, V, Inverted V, K, and Eccentric bracing. Each model was evaluated under seismic loading conditions to assess critical performance parameters such as lateral displacement, story drift, and base shear. The results indicate that the incorporation of steel bracing systems substantially improves the building’s seismic response, and that the type and positioning of the bracing members have a significant influence on enhancing overall lateral stability and deformation control.
