Dynamic Response of Bridges
Abstract
A calculation procedure is developed for predicting the dynamic response of a bridge to a given set of vehicle wheel loads. The method involves convolution of the vehicle loads with modal responses of the bridge. The convolution integral is solved by transformation to the frequency domain using the fast Fourier transform. The method is then extended by an iterative procedure to include dynamic interaction between the bridge and an arbitrary mathematical model of a vehicle. Examples are presented to illustrate the effectiveness of the convolution method, and to demonstrate the convergence of the iterative procedure.
