铁路旅客站房圆柱面壳结构的地震响应分析OACSTPCD
Seismic Performance Analysis of Cylindrical Shell Structure of Railway Station
随着高速铁路的快速发展,中、小型旅客站房逐渐增多,圆柱面壳结构具有兼顾车站服务功能和造型美观的优点,在站房工程中应用较多,需对西部高烈度区圆柱面壳结构的抗震性能进行研究.本文结合西部某车站工程,建立主站房结构的三维有限元数值模型,通过计算结构在遭遇罕遇地震下的动力时程响应,对结构关键部位的位移、加速度、应力响应以及结构薄弱区的破坏形式进行了分析.结果表明:结构中间区域对结构整体的地震响应影响较大,结构的薄弱部位位于中间壳体的柱脚和梁柱节点处;在遭…查看全部>>
With the rapid development of high-speed railway,the number of small and medium passenger station buildings is increasing gradually.Cylindrical shell structures are widely used in station buildings due to their functional service capabilities and architectural aesthetics.However,the seismic performance and mechanical properties of cylindrical shell structures used in western regions with high seismic intensity need further investigation.A three-dimensi…查看全部>>
