Spectral Characteristics of Pedestrian Loads Under Different Crowd Densities Based on the Modified Bipedal Walking Model

Walking speed is influenced by crowed density, which further affects the spectral characteristics of walking forces. Based on the fundamental relationship between walking speed and crowd density, and combined the modified bipedal walking model, this article studies the spectral characteristics of walking forces under different densities, and compared simulation results with relevant experimental statistics. Results show that the changing of crowd density has significant influence on first-order DLF, but little on highorder DLFs, which are consistent with experimental results.
