Steady Vibration of the Double Euler-Bernoulli Beam System under a Moving Load with Uniform Velocity
Based on the Winkler assumption for the elastic foundation, a double Euler-Bernoulli beam system was presented in the form of two partial differential equations, and the analytic solutions of the steady vibration were obtained under a moving load with uniform velocity. Then, by an example, the analytic solution would be compared with the solutions of FLAC, and results showed their consistent rules. Dynamic analytical solutions were then degenerated into the static solution. When the upper beam stiffness tended to infinity, static solution was simplified as the form of double elastic foundation; when the lower beam stiffness tends to infinity, static solution was simplified as common single-layer elastic foundation form. Accordingly, this method provided theory basis for coupled vibration analysis of soil - structure caused by the traffic load in elastic half-space.
