【摘要】 新建的武汉火车站是特大型火车站,它将大跨结构、多层钢结构、桥梁结构融为一体。结合建筑特点对屋面与楼面结构体系进行了选择,并对主要结构的受力特点进行了分析。在屋面结构中,采用拱与网壳杂交的"拱-壳"组合体系,而拱与网壳采用V形撑进行连接。楼面结构与屋面结构的间接结合,降低了主要构件的受力。工程采用的结构体系对于其他大型公建,特别是大型高架车站具有很好的借鉴意义。更多还原

【Abstract】 Wuhan railway station is combined with long span structure,multi-story structure and bridge structure.How to select the floor and roof structure system according to the architectural characteristic is presented.The structure characteristic of main elements is analyzed.In the roof,the "arch-shell" combinatorial system is adopted,the arch and the latticed shell is linked with the latticed shell by V branch.The inner force of main structure is reduced by the indirect combination of floor and roof structure.The structure system of the project can supply reference for big-scale public works,especially for elevated railway station.更多还原
