Abstract
In this paper, improved moving element method (IMEM) is intended to analyze the dynamic response of the beam resting on the two-parameter viscoelastic Pasternak foundation subjected to the moving load and considering effects of beam roughness. Beams are modeled by moving elements, while the load is fixed. The differential equation of motion of the structural system is established based on the principle of virtual public balance and solved by means of numerical integration based on the Newmark algorithm. The characteristic parameters of the foundation and the loads are investigated in order to analyze the dynamic response of the beam such as the second parameter of foundation, the roughness of beam, the velocity and acceleration of moving load.
