Abstract: Wujiang Transportation Hub project includes a total of 5 towers including  hub main building and  residential towers. The main building of the hub has a novel and unique architectural shape, and the spatial relationship of the buildings is relatively complex. The main structure for the hub main building adopts a three-story frame structure. The structure of the atrium area  is complex. It is a large-span spatial cantilever truss with hanging structure. The large-span length of the truss is about 40m and the cantilever length is about 22m. The partial structures at 2-story and 3-story floors are supported by hanging columns. Performance-based method was used for the seismic design  by using YJK and LS-DYNA software. The design ideas and analysis process of the large-span spatial cantilever truss, the floor for the large-span cantilever truss area, the connection design of the truss and the surrounding structure, and the structural design for the 2-story and 3-story hanging columns and vibration for the slab were expounded.For the technical difficulties in the analysis process, corresponding solutions were proposed.  The analysis results show that the design of the large-span cantilever truss structure and the hanging column structure is safe and reliable, which has good seismic performance, and can meet the requirements of the code. The floors for lower chord of cantilever truss and hanging column structure area were strengthened by corresponding structural details and construction measures. 

Keywords:Wujiang Transportation Hub； large-span spatial cantilever truss； hanging column； floor cracking； connection design
