Parametric study of the interaction of bridges and moving vehicles

In this paper we develop a mathematical model for the analysis of the dynamic response of a bridge structure as it interacts with moving vehicles. The vehicles are modeled both for fixed axle distances (e.g. Cooper Loadings) and for variable axle distances (e.g. multi-vehicles). We then generate an algorithm to solve the resulting equations of motion. Results obtained using our theoretical model are shown to compare very well with measured field data.Associate Professor of Mech. Eng.Professor of Mech. Eng.Associate Professor of Civil Eng.
