A concise methodology for evaluating the predisposition of a structure to progressive collapse is presented in this paper. A graphical modeling aid may be developed and used to investigate the potential for progressive collapse by evaluating the maximum ductility and corresponding rotations of critical structural load-bearing elements. Thus, a conventional dynamic computation with initial conditions can give an indication of the potential for progressive collapse of a structure.
