［摘要］汶川地震中，樓梯震害嚴(yán)重，樓梯的抗震設(shè)計(jì)及樓梯對(duì)整體結(jié)構(gòu)抗震性能的影響受到更多關(guān)注。本文簡要介紹了樓梯的震害特征、帶樓梯框架結(jié)構(gòu)的抗震性能、滑支樓梯構(gòu)造和帶滑支樓梯框架結(jié)構(gòu)抗震性能的部分研究成果，總結(jié)了不同樓梯構(gòu)造措施對(duì)樓梯和主體結(jié)構(gòu)抗震性能的影響。對(duì)滑支樓梯的研究工作進(jìn)行了進(jìn)一步探討。

［關(guān)鍵詞］鋼筋混凝土框架結(jié)構(gòu)； 樓梯； 滑支樓梯； 震害； 抗震性能

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
