Abstract:
In this paper a method for damage identification in bridges employing neural networks is presented. In this work, in order to increase the speed and reduce the computational error for damage detection a newtwo stage method is introduced. In the first stage the damages are localized using a radial basis functionneural network which has the benefit of high learning speed. In the second stage, the exact location and severity of damaged elements found using a well-trained back propagation neural network which possesses high powerful learning capacity. In order to evaluate the proposed method Louisville trussbridge in United States of America is modeled by a finite element program and then changes in the responses is analyzed using MATLAB neural networks toolbox. Numerical results demonstrate the efficiency of the proposed method for correct damage identification
