The structures which seem to be strong may collapse during an earthquake. This was the case of the Pyne Gould Corporation building in New Zealand, which collapsed during the February 22, 2011, earthquake. Its collapse raised questions about the performance of the structure under seismic loading. The seismic performance evaluation of the nonlinear static analysis, or the pushover analysis, is the first choice due to its simplicity. The evaluation assumes that the structure vibrates in the first or lower mode of the vibration during a seismic event. The idealization of multiple degrees of freedom (MDOF) system to an equivalent single degree of freedom (SDOF) is the basic concept of pushover analysis. Despite these underlying assumptions, it has led to the excellent prediction of the seismic response of the multiple degrees of freedom system; which is the reason for the popularity of the pushover analysis. In this study, the pushover analysis of two multi-storied buildings in New Zealand has been done. The first building is the typical residential building, while the other is the mixed-used office building, the Pyne Gould Corporation building (PGC). The nonlinear response of the RCC buildings using the finite element analysis programs SAP2000 and ETABS under the loading has been carried out with the objective to investigate the behavior of the building. The global behavior of the structure is analyzed using the performance point of the structure while the careful analysis of the plastic hinge formation depicts the real behavior of the structure and its elements. Through pushover analysis, potential weak areas are identified with the examination of hinge state at the different steps. The application of the pushover analysis helped to verify the weak elements in the building which were the cause of the building's collapse. The method can be implemented to understand the structural behavior of the structural members after some damage so that the designer is able to make use of the structural behavior when it receives damage to avoid total collapse.
