[摘要] 该卧式煤仓的侧向刚度变化较大，由计算可知刚度突变的楼层即为结构的薄弱层，应注意地震作用下的结构整体性能分析。本文采用有限元软件MIDAS，对国内首个万吨卧式煤仓结构的抗震性能进行了反应谱分析。并对结构选型、载荷取值、结构分析进行了详细介绍，对以后的同类结构具有一定的借鉴作用。

Abstract: The horizontal coal bunker larger lateral stiffness change,  we can see by calculating the stiffness of the floor is the structure of mutation in the weak layer, should pay attention to the role of seismic structure under the overall performance analysis. In this paper, finite element software MIDAS has adopted to the first 10,000 tons of domestic coal bunker structure of horizontal seismic performance of the response spectrum analysis. Selection of the structure, load value, structural analysis camed out a detailed introduction of the future must have a similar structure of the guiding role.
Keywords: horizontal coal bunker; lateral stiffness; seismic performance; response spectrum analysis
