In the present study, the demand capacity ratio (DCR) of thirteen storey RC framed symmetrical and unsymmetrical structures are evaluated as per U.S. General Services Administration (GSA) guidelines. The Linear static analysis is carried out using software, ETABS V13 according to IS codes. To study the progressive collapse of a structure, typical columns are removed one at a time, and continued with design and analysis. When columns at different locations in a symmetric and unsymmetrical building was removed among the intersecting beams the shorter span tend to take the extra burden load and DCR values of shorter span beams were more compared to longer span beams. The DCR values obtained show that columns of both symmetric and unsymmetrical structure are safe and beams of both symmetric and unsymmetrical structure to be reinforced additionally.
