Abstract :
Progressive collapse is a phenomenon that begins with initial local damage, due to unusual loading or design and construction errors, and leads to collapse of a large part or the entire structure. Of course, the progressive collapse phenomenon will rarely occur during the useful lifetime of the structure. However, this issue can cause a lot of financial and life damage, thus it has become a major challenge in structural engineering. In this study, the structural models were steel plate shear wall with different configuration and moment frame systems with 5, 10 and 15 stories, which were designed in SAP2000 V.19 software two dimensionally according to code regulations and then the nonlinear dynamic analysis was performed in finite element ABAQUS software. The Alternate Path Method (APM) is used according to UFC4-023-03 guideline in this study, which is the most economical and rational method. Considering the displacement and rotation values of the members due to the column removal and the frame ductility, and failure damage indices, the most important results indicate that the probability of occurrence of progressive collapse due to the corner column removal of the 5-story moment frame is more critical than other frames and also, a proper and similar performance was observed due to the corner column removal in steel plate shear walls with the configurations examined
