Abstract: Skeleton-supporting ETFE cushion membrane structure is used in Dalian Sports Center Stadium’s canopy shell. Cushion structure covers more area than Germany Allianz Arena and it is currently the second largest cushion structure after the ‘Water Cube’ in Beijing. Design and analysis of skeleton-supporting structure and cushion structure were introduced in detail. First, static and dynamic characteristics of the steel truss were analyzed in detail based on different load conditions. Based on this, response analysis of the steel truss under frequent and intermediate earthquakes was conducted using response spectrum method and time-history analysis method respectively. Dynamic elastic-plastic time-history analysis under rare earthquake was carried out as well. Conclusion is drawn that the steel truss has enough strength and stiffness reserve. Moreover, the stability analysis of the structure was conducted with the consideration of geometrical and material nonlinearity. The results show that the stability of the structure can meet the demands of code. Finally, the basic parameter determination, the design and the joint construction of the cushion structure were illustrated specifically.
Keywords: Dalian Sports Center; canopy shell; steel truss structure; cushion structure
