Abstract

If in the event of a critical incident, by eliminating a structural element, a comprehensive damage occurs, such a phenomenon is called progressive collapse. At the moment of explosion, redistribute the carried load by members of damaged structural element or the adjacent members may Lead to excessive tension or exceed the load capacity of the other members of that damage is the result of diffusion. To study the phenomenon of progressive collapse and structural robustness index under blast loading, four types of structures with RC moment frame with shear walls in four, seven, twelve, and fourteen story level, which all of them have the same plan, have been considered. In the above-mentioned buildings, Some structural elements have been removed and the impact of these scenarios on the dynamic behavior of structures during the explosion has been examined. In this study, the potential and capacity structures against the progressive collapse and the failure modes using local dynamic analysis of the explosion has been determined. Also, robustness structural Index has been evaluated. So the analysis to find the most likely failure mode for development improvement purposes, it is possible that could result in structures with higher reliability in a seismic zone.
