摘　　要：以鞍山站上部网架屋盖-支座-支承框架结构为研究对象,系统地研究了网架屋盖与下部支承结构共同工作问题,总结和分析了现行网架结构设计的一些问题,通过有限元分析软件Midas,对鞍山站站房屋盖网架采用固定铰支座、弹性支座和整体分析等多个模型计算对比,结果表明下部支承结构的刚度、设置橡胶支座对上部网架屋盖的地震反应有较大影响。Aiming at the upper truss roof-bearing-supporting frame structure at Anshan railway station,this paper conducts an systematical study on the combined act of the truss roof structure and lower supporting structure,summarizes and analyzes issues concerning current truss structure design,and carries out calculation and comparison with Midas finite element analysis software for such models as fixed hinged bearing,elastic bearing and integral analysis applied to station building roof truss.The results have shown the impact of the rigidity of the supporting structure and the rubber bearing on the upper truss structure in response to earthquake.
