The present paper proposes modern approaches, nonlinear static and dynamic analysis procedures based on the Applied Element Method, to assess a progressive collapse problem of a RC frame structure with infill walls. Comparisons between the results of modeling alternatives for a 6-story building: bare frames, exterior frames with infill full walls, openings or with windows (casement and glass) for two different columns removal approaches (demolition and blast scenarios) were made.
