松陵枢纽综合体主体结构设计

Main structure design of Songling comprehensive transportation hub

本工程为一交通枢纽综合体。由于建筑功能需要,导致了结构体系中出现了转换梁、转换柱、穿层柱及楼板大开洞等薄弱部位。另外由于建筑造型需要,出现了大跨开敞公共空间,从而使结构产生了大跨度、长悬臂以及悬挂结构。本文重点介绍了主体结构的设计特点。对主体结构进行了弹性时程分析,对部分重要和受力复杂构件进行性能化设计,计算结果表明,结构的各项指标均符合规范要求,具有良好的抗震性能,结构安全可靠。

The project is a comprehensive transportation hub. Due to the need of building function, there are weak parts in the structural system, such as transfer beam, transfer column, through floor column and large opening in floor slab. In addition, due to the needs of architectural modeling, there is a long-span open public space, resulting in a long-span, long cantilever and suspension structure. This paper focuses on the design characteristics of the main structure. The elastic time history analysis of the main structure is carried out, and the performance-based design of some important and complex components is carried out. The calculation results show that the indexes of the structure meet the requirements of the code, have good seismic performance, and the structure is safe and reliable.
