Nonlinear Push-Over Analysis of Reinforced Concrete Structures Incorporating Steel Braces

Pushover analysis is a nonlinear static method employed to estimate structural deformation under seismic forces. This process involves incrementally applying lateral loads in a predetermined pattern to the structural model, increasing the load step by step until the structure fails. The outcome of this analysis is a force-displacement curve, which shows the relationship between applied forces and the resulting displacements. This research investigates a symmetric 12-story reinforced concrete (RC) building with different steel bracing configurations. The analysis is conducted using SAP 2000 software, considering Dead, Live, and Seismic loads as specified by IS 1893-Part-1 (2002). The structural design adheres to the provisions of IS-800.
