［摘要］宁夏科技馆主展厅，柱网8.4m×12.0m，地下1层，地上3层，首层层高8m，层2，3层高7m，结构采用钢筋混凝土框架剪力墙结构，主-次梁楼盖体系。根据建筑功能及造型要求，工程中采用了钢混凝土组合楼盖、屋面钢梁、异型网壳、球面网壳等结构形式。对结构体系及楼盖体系的造型进行了分析比较，介绍了几种型钢结构与混凝土主体结构的连接节点做法及构造加强措施。通过屈曲分析研究了支座约束对单层异型网壳稳定性能的影响。
［关键词］结构体系；楼盖体系；钢-混凝土组合楼盖；异型网壳

Abstract:Frame-shear wall structure is adopted in Ningxia science and technology museum building with main and secondary girder roof system. The column grid is 8.4m×12.0m with one storey underground and three storey overground. The height of the first storey is 8m and that of the second and third storey are 7m. To meet the service function and architectural style, various structural types are adopted including steel-concrete composite slabs, steel beam on the roof, latticed shell jointly deformed and latticed dome. Buckling analysis is adopted to study the stability of latticed shell jointly deformed.
Keywords:structural system；roof system；steel-concrete composite slabs；latticed shell jointly deformed
