ABSTRACT
This paper aims to provide a reliable characterization of pedestrian-induced loading on footbridges in bidirectional restricted traffic condition. Numerical simulations of bidirectional pedestrian traffic are carried out through an agent-based model, considering variable pedestrian densities and deck widths. The probability distribution of the step frequency and the power spectral density function of the modal load are obtained numerically. Analyses show that in bidirectional traffic pedestrian interactions cause a significant variation of pedestrian step frequency in time, which remarkably affects the harmonic content of the loading.
