Mitigating Progressive Collapse Risk in Multi-Story Steel Building Incorporating Buckling Restrained Brace (BRB)
Progressive Collapse is a phenomenon when a structural failure of a key component leads to the collapse of the entire structure. This can occur when the structure experiences unexpected loads that it was not designed to handle. To evaluate the potential for progressive collapse, a study was conducted on a 9-storey steel building using the U.S. General Services Administration (GSA) 2016 guidelines. The study evaluated the potential for progressive collapse under three scenarios of the removal of columns and/or bracing from the ground floor. Linear static, Non-linear static, and Non-linear Dynamic analysis were performed using ETABS software. Buckling Restrained Braces were used to evaluate the progressive collapse potential of steel-braced buildings. Buckling Restrained Brace has the same behavior in both tension as well as compression. Chevron Bracing (INV-V), 2 Story X Bracing (2XBF), and V Bracing are considered for the present study. Six different Bracing location is considered for this study. As a result of the linear static procedure, the Demand Capacity Ratio (DCR) was computed for structural components such as beams, columns, and bracing. A Load–Displacement plot was generated from the results of the nonlinear static analysis. By introducing Buckling Restrained Brace (BRB) systems in multistory steel buildings, the study found that the structures’ resilience against progressive collapse can be significantly improved.
