Abstract

Bridge vibrations produced from a crowd of pedestrians are typically estimated by using an enhancement factor applied to the effect caused by a single pedestrian. In this paper a moving force model is used in Monte Carlo simulations of non-homogeneous single pedestrians and crowds to estimate characteristic vertical vibration levels. Also, statistical distributions of the bridge parameters are considered, including flexural rigidity, mass, and rotational stiffness at the supports. In this paper, probability of serviceability failure is calculated for ranges of pedestrian and bridge input parameters and it is found that the addition of statistical ranges for bridge parameters has only a small effect on the vertical acceleration response of the bridge deck. It reduced the probability of serviceability failure for a bridge with a natural frequency of 1.8, 1.96 Hz and 2.2 Hz subjected to the loading of a characteristic single pedestrian.
