Comparison of Theoretical Dynamic Analysis of the Footbridge with Experiment
Original language description
This paper is aimed at dynamic analysis of the footbridge, which was excited by pedestrians and crowd of vandals. Mathematical models of pedestrians were considered as harmonic forces, which were moving over the structure with constant velocity. Second approach for description of loading, induced by pedestrians, was the Rimless wheel model, which takes into account kinematic aspects of trajectory of human body?s centroid during walking and it is based on the motion of inverted pendulum. Models describing action of vandals were considered as force defined by periodic triangular pulses and viscoelastic SDOF model of human body, which was activated by kinematic excitation of the contact point between SDOF model and structure. The investigated structure statically acts as simply supported beam. It is slab-on-girder bridge with steel girders and concrete deck. The response was evaluated by using modal decomposition techniques with theoretically obtained mode shapes. Computed results were co
