According to the kinematic hardening theory and the cyclical loading model of concrete filled steel tubular,authors present the relationship between stress and strain in the multi stress states to CFST. With the method of nonlinear finite element, a certain CFST arch bridge is researched on its dynamic nonlinear response due to the moving vehicle, and the deep investigation of the effect of nonlinear material behavior of CFST on the vibration of vehicle bridge has been performed successfully to get excellent results.
