Dynamic Behavior of Cable-Stayed Bridge under Moving Vehicle and Train

In this study, dynamic behavior of cable-stayed bridge under moving vehicle and train was analyzed. The parameters considered are the main span length of bridge and the existence of intermediate pier at side span. For the parametric analysis, cable-stayed bridges with 400m and 700m main span (with and without the intermediate pier at side span) were selected. From the vehicle/train-bridge interaction analysis, the intermediate pier was found very effective to reduce the dynamic amplification of girder and stay-cables.
