Abstract

Taking the temperature effect and geometric nonlinearity into consideration, the nonlinear vibration equation of prestressed fish-shaped cable truss support system in point-supported glass curtain wall was derived by assuming the support system as a continuum membra. By the Galerkin method, the partial differential equation was transformed into ordinary differential equation which was solved with L-P method and KBM method. The effects of temperature, amplitude, and exterior excitation on the nonlinear vibration were discussed with the engineering example. The result indicates that frequency of prestressed fish-shaped cable truss support system in point-supported glass curtain wall will decreases, which resulted in the increases of temperature, and the vibration shows hard spring characteristic.
