Abstract:Located in the top of the main peak of Beijing Pinggu Shilinxia, Shilinxia observation deck adopts cable-stayed structure. The structure system and characteristics was introduced. The MIDAS/Gen was uesd for structural modal analysis and nonlinear analysis, and nonlinear buckling analysis was carried for the main arch. The analysis results show that the  overall structural system is reasonable; the arrangement and initial pretension setting of cable is reasonable; the security and comfort of the structure is assured.

Keywords:Shilinxia observation deck; cable structure; nonlinear analysis; buckling analysis
