Nonlinear Static Analysis for Progressive Collapse Potential of RC Building

Abstract

In this study, the progressive collapse potential of a 10-storey concrete frame structure was investigated using nonlinear static analysis. 15 different cases were considered and their performances were compared with each other. From the nonlinear static analysis results, most of longitudinal beams in upper floors and slabs above the failure column would collapse as the results of removing an exterior column, no beams and slabs would collapse when an interior column at ground floor was removed, and only the short-span beams in superstructure would collapse when an interior column in upper floors was removed. Tie force reinforcement along floors and beams of edge span can be used to avoid the progressive failure of floors, after failure of particular column.
