Abstract

The nonlinear static pushover analysis is one of the methods used to study structures exposed to the influence of seismic ground motions. Extensive

research has been conducted over time to improve the results of this method on high structures. In this article, some of non-adaptive pushover analysis methods were reviewed, and then applied to two reinforced concrete frame structures of two different heights ,20 and 25 floors,and compared the seismic response (story drift) with the nonlinear time history analysis method, which is considered the most accurate method for estimating the seismic response .

The study showed that using the NADP method is the best among non adaptive pushover analysis methods for high structures , in which the effect of the high modes is clear .The study also showed that all non adaptive pushover analysis methods overestimated the seismic response in the lower floors while underestimatied it in the upper floors.Therefor , it is necessary to search for more accurate nonlinear static pushover analysis methods so that their results close to the accurate dynamic method for high concrete structures.
