芦山地震楼梯间震害调查及思考
|
摘要
楼梯间作为地震中人员疏散和救援通道,其抗震设计应引起足够的重视。我国2010年实行的《建筑抗震设计规范》(GB50011-2010)中加强了结构中楼梯间的设计要求,结合该规范的实施,本文总结了芦山地震中各类结构中楼梯间的震害现象。通过对梯板、楼梯间墙体、与楼梯间相连的主体结构等位置的震害分析,指出了规范中关于楼梯间新增条文的必要性;提出了一些抗震设计建议,为规范修订和工程设计提供参考。
In an earthquake,the staircase is designed as a passage of evacuation and salvation.As a result,more attention on the basic seismic design of staircases should be paid.In the " code for seismic design of buildings"(GB50011-2010),the seismic design requirement of staircase is specifically raised.With the code for seismic design of buildings,different kinds of staircase damage caused by the Lushan earthquake are summarized in this paper.Through the analysis of the seismic damage to staircase slab,staircase wall,and main structures connected with the staircases,the necessity of adding new terms to the seismic code is pointed out.The suggestion for the seismic design of staircases is presented,which provides a reference for code revision and engineering design.
