✦ Synopsis
This paper deals with the linear dynamic response of a simply supported light (steel) bridge under a moving vehicle of constant magnitude and velocity. This analysis focuses attention on the usually neglected in#uence of the centripetal force, Coriolis force and vehicle's rotatory inertia. The individual and coupling e!ects of these forces on the dynamic response of the bridge in connection with the magnitude of the velocity of the moving vehicle are thoroughly discussed. A variety of numerical results allows one to draw important conclusions for structural design purposes.
