Effect of eliminating the column on progressive collapse on seismic performance in dual steel structures

Progressive collapse is usually defined as follows: the expansion of an initial local damage within structures as a chain chemical reaction that led to the partial or total collapse of the structure. Studies in relation to the failure of structural systems in recent years highlight the importance of...
