Abstract

The nonlinear static analysis method has facilitated models closer to the structural response for strong seismic movements. Therefore, an evaluation of the seismic performance of a multipurpose room building located in a public national university in Chiclayo-Peru was developed by applying nonlinear static analysis, which contains two similar modules of 3 levels each with irregular floors. The structural system of the building is made of bearing walls, it was built in 2010 and was designed according to E.030 (Peruvian earthquake resistant norm) and with the seismic microzoning of Peru. For practical purposes, taking into consideration the symmetry of the global structure, one of the modules was evaluated using nonlinear methods that can simulate the effect of earthquakes on the building using distributed loads on each of the levels. This development included the application of a linear analysis to establish the response spectra and from there implement the nonlinear Pushover analysis. With the results of the analysis, the plastic ball joints of the structural elements of the building were evaluated for both directions. Based on the results, the performance in both directions was determined taking into account the performance levels of HAZUS and VISION2000. The results show a performance of "Life safety" and "Close to collapse" in the X and Y direction respectively, in addition to that, drifts also show a close relation with performance data because HAZUS shows that Y drifts are not favorable, therefore, it is necessary to execute a reinforcement.
