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。
Main Hall of Ningxia Science and Technology Museum, column network 8.4m × 12.0m, 1 underground, 3 above ground, the first floor of 8m high, the second and third floors of 7m high, the structure of reinforced concrete frame - shear wall structure, the main - Beam floor system. According to the architectural functions and modeling requirements, the project uses steel-concrete composite floor coverings, roof steel beams, shaped reticulated shells, spherical reticulated shell and other structural forms. The structure of the system and the floor system were analyzed and compared, and several types of steel structure and the concrete structure of the main structure of the connection practices and construction measures to strengthen. The buckling analysis is used to study the influence of the support constraint on the stability of a single-layer deformed reticulated shell.
