Abstract:The dynamic stability characteristic of tensioned cabletruss (TCT) at horizontal period load is analyzed. To control dynamic response of TCT, the viscoelastic damper (VED) is used in this kind of structures, the optimization design method of the VED is obtained, and the vibration control design curve of TCT with VED is presented. Nonlinear dynamic timehistory analysis software is compiled for the TCT structures.The software can be used to analyze the nonlinear dynamic response of prestressed steel structures with VED, and  provides a reliable design method and  analysis tool for the vibration control of TCT.
Keywords:tensioned cabletruss; nonlinear timehistory analysis; dynamic stability; vibration control; viscoelastic damper
