Abstract

In recent years, performance analysis of the structures has become more of an issue, in parallel with the developments in earthquake engineering. Different types of methods are developed for the assessment of the performance of the structures under earthquake loads. Among these methods,due to being uncomplicated, nonlinear static analysis methods became prominent and took parts in Earthquake Codes. In nonlinear static analysis methods, pushover curve is used to identify the behavior of a structure. In this study a practical method for the determination of the pushover curves of multistory structures is suggested. In the study initially the method and the assumptions are presented afterwards examples are solved to investigate the reliability of the method. In the examples, static pushover curves are obtained by the proposed method and compared with the pushover curves which are obtained by detailed method. Comparison of the results indicates that the ones obtained by the presented method are in good agreement with the ones which are obtained by detailed method.
