Abstract

Seismic progressive collapse conceptually means that during an earthquake event, some of the key elements of the structure reach the threshold of premature failure, for example, due to explosion caused by earthquake or design/operation problems. This process results in removing the damaged elements, redistributing unbalanced internal forces/moments, and increasing the stress in the adjacent elements, which is followed by local and/or global collapse of the structure. In this study, the seismic progressive collapse potential of steel moment frames with different structural systems was evaluated. 3-storey steel frame structures were simulated by the nonlinear beam-column element model with distributed plastic hinges that were available in the OpenSees Software. Nonlinear dynamic analyses were done on the models subjected to the earthquake records. The progressive collapse was then assessed using the statistical analysis and graphical results' interpretation/presentation in Excel Software and MATLAB Program. The structural systems included bending moment-frame systems, concentrically- and eccentrically-braced systems, as well as knee-braced system. The removal of the side-column resulted in higher value of the seismic response; the reason was that the side-column was linked to the frame only due to the beam connected to its upper node.
