Abstract
This paper is aimed at investigating the dynamic response of a compound beam subjected to moving loads at high speeds. The compound beam structure is composed of a simple beam and a twomember truss connected by a set of rigid bars at the midpoint of the beam. Based on the nonlinear elastic theory of a symmetric twomember truss under the action of a vertical tip load, and the incremental-iterative solution procedures for solving a nonlinear dynamic system, the dynamic response of the compound beam structure under the excitation of moving loads is studied. According to the numerical results, the nonlinear effect of vibration is not so obvious to the response of the beam but the installation of a two-member truss system in a simple beam may significantly results in smaller dynamic response of the compound beam structure under the passage of moving loads at high speeds.
