Comparison of current models for excitation of footbridges due to walking pedestrians and vandalism with experiment
Original language description
This paper is focused on a theoretical analysis of dynamic behaviour of the footbridge across the Opatovicka Street in Prague. The numerical analysis of forced vibration is performed for loads, which represent walking and running pedestrians and a crowdof vandals. The models for pedestrians, acting on the structure, are considered as harmonically varying force placed in the most efficient point of the footbridge deck (Dynamic Loading Factor), defined by different authors. Models describing acting of vandals are considered as semi ? sinusoidal impulses, periodical triangle pulses and a harmonic force derived from the Fourier´s Series (Bachmann?s model). The footbridge was chosen for the dynamic analysis due to the fact that the footbridge is acting asa simply supported beam and that its first natural bending frequency is in the interval (1 - 3) Hz. It means that a resonance of structure vibration due to the human walking (running) frequency could arise. According to the value of the f
