| Abstract: | The suspendome is a type of spatial structure composed of the single-layered grid shell and the prestressed cable-strut system.Based on the design of a gymnasium roof,the loading behavior of the suspendome has been investigated in this paper,including the initial state analysis,load state analysis,as well as seismic action analysis.The process of the design of the suspendome has been analyzed,and the values of prestress in the cables were designed.The results indicate that this form of suspendome has good l... |
