The Effects of Different Amplitude-Dependent Damping Models on Wind-Induced Response of a Tall Building
Guangzhou West Tower (GZWT) is the second tallest building in China with 432m height. Based on the 3-D finite element model of this building, a reduced finite element model was first established for the wind-induced vibration analysis in the paper. Several models for the amplitude-dependent structural damping and aerodynamic damping ratio were adopted to evaluate the nonlinear damping effects on the wind-induced response of this building by using the surface wind pressure record in wind tunnel test. Wind-induced responses evaluated by amplitude-dependent damping were compared with those obtained from constant damping ratio assumption through the comprehensive studies for several wind load cases.
