The Effects of Centripetal and Coriolis Forces on the Dynamic Response of Light Bridges Under Moving Loads

Abstract

This paper deals with the linear dynamic response of a simply supported light (steel) bridge under a moving load-mass of constant magnitude and velocity including the effect of the centripetal and Coriolis forces, which always are neglected. The individual and coupling effect of these forces in connection with the magnitude of the velocity of the moving load are fully discussed using a solution method based on an author's older publication. A variety of numerical results allows us to draw important conclusions for structural design purposes.
