摘要
以青岛地铁13号线古镇口站高架车站为例,对地震参数的选取、不同重现期下结构性能等级规范限值要求等做了详细的介绍,设计采用PKPM和Midas Civil两种软件对应GB 50011-2010《建筑抗震设计规范》、GB 50111-2006《铁路工程抗震设计规范》进行抗震分析,并通过弹性动力时程法和振型分解反应谱法对比计算,结果表明:对于地面两层“桥建合一”四柱框架高架车站结构,两种不同软件计算结果均满足规范相关要求;弹性动时程法最大楼层地震剪力均小于振型分解反应谱法最大楼层地震剪力,采用振型分解反应谱法进行结构设计的结构计算结果偏安全.
Taking for example the Guzhenkou elevated station of Qingdao Metro line 13,a detailed introduction for selection of earthquake parameters and limits of structural performance classification code during differentrecurrence period is given.In the design two softwares the PKPM and the MIDAS CIVIL are adopted for anti-seismic analysis based on GB 50011-2010"Code for seismic design of buildings"and GB 50111-2006"Code for seismic design of railway engineering"respectively,and comparison and caleulation ure given for the clastic dynamic time history method and the mode-decomposition response spectrum method.The results show that,as for the four-columnframe elevated station structure of two-storey"combination of bridge and building"on the ground,the calculation results of the two different softwares can all meet the code requirements;the maximum seismic shear force of floor by the elastic dynamie time history method is smaller than that by the mode-decomposition response spectrum method,and the structural calculation results of structural design by the mode-decomposition response spectrum method are safer.
