heal.abstract	The dynamic behavior of infinite beams resting on elastic foundation under the action of moving loads is examined. The beam is made from a homogeneous and isotropic material with modulus of elasticity E and is resting on an elastic foundation. The elastic foundation is assumed to be of the Winkler type such as the foundation reactions are directly proportional to the deflections of the beam. The corresponding Winkler constant is, k = 0.004 × 108. A very thin and feeble concrete beam with cross-section A = 0.125 m2 and EI = 0.20 × Nm2 is based on this kind of soil and the corresponding critical speed is 285 km/h. The proposed formulae are accurate for subcritical speeds either with or without damping.	en
