THE STRUCTURAL DESIGN OF SHOUGUANG STADIUM

The Shouguang Stadium is a long-span cable-suspended space structure.The inner of roof is suspended by cable from the mast,and the outer of the roof is placed on the concrete column of the stands.The roof is a joint-and-girder space truss system.It was introduced the structure system,the load distribution,the design method of two key aspects(cable and sliding support),it was also compared the design controlling data to the monitoring data during construction.The results show that the preloading force of cable and the displacement of the sliding support.For the cable-suspended structure,the preloading force should be applied to avoid the inactivation of the cable under the wind loading.For long-span space structure,the seismic performance can be improved and the cost be saved by changing the restraint mode of the support and selecting the force-transferred path appropriated.
