摘要:

2008年的汶川地震及2010年的玉树地震震害结果表明,钢筋混凝土框架结构楼梯间破坏严重,致使许多人逃生受阻。本文以框架结构楼梯间地震灾害调查结果为根据,分析了地震灾害发生时楼梯间的破坏机制,破坏主要发生于梯段板、框架柱、 梯柱、梯梁及平台板,进而提出了楼梯进行抗震设计的必要性。通过对现行规范的分析,结合近几年来的研究成果,提出了有利于抗震性能的几点设计建议。

Abstract:

The damage results of the wenchuan earthquake in 2008 and the yushu earthquake in 2010 show that the staircase in frame structure has been destroyed seriously, which jammed the withdraw way .The paper, based on the findings of actual earthquake damage survey of the staircase in frame structure, analyzed the mechanism of stair damage in the previous earthquake ,the damage occurs mainly in stairway flight, frame column, stair column, stair beam and platform plate and then indicated the necessity of seismic design for stairs. By analyzing of the current code and combining recent years research, proposed several design suggestions which will help to improve the seismic behavior.

Key words: frame structure, staircase, seismic design, design suggestion
