| Abstract: | Shenzhen University Xi-Li gymnasium is composed of steel roof stucture and RC frame. The steel roof is supported by 28 RC columns with about 60m spans in two directions. The roof presents a polyline shape in the east-west direction section and variable thickness shape in the north-south direction section. The two-way diagonal and double-layer space truss structure is adopted to the steel roof structure. According to the characteristics of the proposed structure, this paper introduces., the selection calculation of the double-layer roof structure, design load, the characteristic of structure, the truss member sections and the key joint design. It may provide references for similar structures. |
