The progressive collapse of the building occurs when one or more vertical load-carrying structural elements like columns and shear walls are removed. Once a column is removed due to an extreme load generated either by natural hazards such as earthquake or by manmade like gas explosions, terrorist attacks, impact by vehicles, etc. The weight of the structure transfers to neighboring columns in the structure. In this current study, the behavior of shear wall –framed buildings with ten stories with flat slab and edge beams. The progressive collapse located in the different soil profile (S C , S D ) is investigated. A linear static analysis is worked out by using ETABS Software Version. 16.2.1. The demand capacity ratio is assessed in the RC portion’s critical region associated with the column removed and shear wall, as per GSA guidelines 2013 and ASCE 41-17 Seismic Evaluation and Retrofit of Existing Buildings [ 1 ]. But now the new version 2019 of ETABS 19. Enhancements provide the output tables have been enhanced to tabulate the demand capacity ratio (D/C ratio) for the whole model, the paper concluded that with the additional reinforcement in columns, there is less susceptibility of progressive collapse, and also a building designed to resist earthquake. The results showed the existence of the column and shear wall in the building makes it resistive to progressive collapse under the loss of vertical load-bearing elements by providing sufficient stiffness and load paths for gravity loads.
