摘要
汶川地震中,楼梯震害严重,楼梯的抗震设计及楼梯对整体结构抗震性能的影响受到更多关注。本文简要介绍了楼梯的震害特征、带楼梯框架结构的抗震性能、滑支楼梯构造和带滑支楼梯框架结构抗震性能的部分研究成果,总结了不同楼梯构造措施对楼梯和主体结构抗震性能的影响。对滑支楼梯的研究工作进行了进一步探讨。
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.
