Utilization of Biodynamic Models of Human Body in Dynamic Analysis of Footbridges

Abstract:

The submitted paper deals with a dynamic analysis of the footbridge, which has been exposed to the effects of vandalism and crossing pedestrians. The loading produced by pedestrians was considered for two typical states. Firstly, the analysis was aimed at the ordinary traffic where pedestrians were discretized by the SDOF damped biodynamic models and secondly, the movement of single pedestrian, which was based on the inverted pendulum and biodynamic properties of human body, was evaluated. The jumping vandals were replaced by the motion of SDOF undamped biodynamic model. The calculations have been done at the computational model of the real footbridge across Opatovska Street in Prague.
