  Structural Integrity Analysis of Reinforced Concrete Frames Under Progressive Collapse Scenarios

  By Pragati Bibhishan Sirsat, R. S. Londhe

  Abstract: This study examines how a tall reinforced concrete (RC) frame may gradually collapse under several column removal situations, such as edge, end, center, zigzag, and two-column failures. The study assesses the structural reaction based on displacement, inter-story drift, and Demand–Capacity Ratio (DCR) using nonlinear static pushover analysis carried out in ETABS. According to the analysis, the frame's stability is seriously jeopardized when two nearby columns and end columns are removed, …
