［摘要］钢-混凝土混合结构能充分发挥钢结构及混凝土结构两种材料的优点，具有良好的受力性能，可较好地满足建筑造型要求，在实际工程中有众多的应用。银川火车站站房即为钢-混凝土混合结构，且结构体系及受力性能较为复杂。针对此类结构分析设计中所遇到的问题，基于整体结构建模分析，采用多软件多方法的分析手段，以确保结构分析结果的准确性和可靠性。另外还探讨了混合结构中钢结构与混凝土结构的相互影响及连接支座参数的确定的问题。

Abstract:Steel-concrete hybrid structure, which can fully exert the advantages of the two kinds of structures and can meet the requirements of building style, has numerous applications in actual engineering for the requirement of architectural function and modeling. Yinchuan Railway Station is the steel-concrete hybrid structure, and the structure and mechanics properties are complex. To solve the problems in hybrid structural design,  multiple softwares and methods were used in design with overall analysis model. The accuracy and reliability of the structural analysis are ensured. The interaction between steel structure and concrete structure in hybrid structure is also discussed.
Keywords:steel-concrete hybrid structure; modal damping ratio; steel structure design; bearing stiffness setting
