Abstract: It was conducted the static nonlinear pushover analysis of a moment frame structure. Through the analysis of the structure basis shearing force-top displacements elastoplasticity change relations, the structure plastic hinges formation course and the destruction mechanism, it was obtained the performance point of the structure. Then it was examined the story displacement of the structure to see whether it satisfied the limit of the story displacement specified by the code GB 500112011, so as to examine and inspect the earthquake resistance ability. Finally the structure failure mechanism was discussed, and the method of improving structure earthquake resistance performance was researched.
