Dynamic analysis of the structure exposed to the moving periodic force and viscoelastic models of the human body

摘要

Submitted paper is focused on dynamic analysis of the footbridge, which is represented by the simply supported beam. The continuous beam model was discretized by the FEM to MDOF system and loaded by pedestrians, walking across the structure. Three models of traffic load are considered in this paper. Firstly, it is the mathematical description of normal pedestrian traffic, where each pedestrian is randomly generated by the Monte Carlo method. Secondly, the movement of single pedestrian, simplified by viscoelastic models, is introduced. Thirdly, the DLF model of vandals with stochastic parameters is investigated as well.
