✦ Synopsis

This paper deals with the linear dynamic response of a simply supported elastic singlespan beam subjected to a moving load of constant magnitude and variable velocity. This analysis focuses attention on the effect of the acceleration or deceleration on the behaviour of the beam under a single (one-axle) load, or a real vehicle model (two-axle load), while the influence of the damping of the beam is taken into account for this last model. A variety of numerical results allows us to draw important conclusions for structural design purposes.

An iterative modal analysis approach is developed to determine the e!ect of transverse cracks on the dynamic behavior of simply supported undamped Bernoulli}Euler beams subject to a moving mass. The presence of crack results in higher de#ections and alters the beam response patterns. In particular,
