Abstract:The structural style of the disk canopy in Beijing software park is rung double deck cable system,in which 288 cables are adopted including radial cables,hanger cables and stabilizing cables. Buckling analysis considering geometry nonlinear and initial defection is done,and the tensioning sequence for cables is confirmed according to the buckling analysis. The tensioning process is divided into 163 steps. The concrete steps for tensioning,the methods used for construction simulation and the equipments used are introduced. The tensioning of the cables is finished and the error is controlled in 5%,which verifies the correctness of the construction simulation.Keywords:disk canopy; cable structure; prestress tensioning; construction simulation
