Comparison of Different Standards for Progressive Collapse Evaluation Procedures
The chain reaction failure of a major portion of a structure that is initiated by the failure of a relatively small portion is referred to as the progressive collapse of a structure. The main approach used for the evaluation of a structure’s vulnerability to progressive collapse is the instantaneous removal of a load bearing element of the structure, followed by studying its effect on other structural elements. An analytical study using a finite element model (FEM) is used in this investigation with the aim of comparing the main two standards that address progressive collapse. A three-dimensional nonlinear model of a concrete generic frame structure is used in the study. The structure is designed according to different seismic zones in order to evaluate the effect of the seismic region on its vulnerability to progressive collapse.
