Abstract: Staircases were severely damaged in Wenchuan Earthquake. Seismic design of staircase and the effects to seismic performance of structures were more concerned. Seismic damages of staircase were summarized. Some current researches on seismic performance of frame structures with staircase, details of slide support staircase and seismic performance of frame structures with slide support staircase were introduced. The effects of staircase details to the seismic performance of staircase and main structures were summarized. Some further researches are proposed about slide support staircase.

Keywords: reinforced concrete frame structure; staircase; slide support staircase; seismic damage; seismic performance
