Modeling of single-pedestrian walking loads based on a walkway test system

Multiple footstep loads and the center of pressure displacement were obtained using the walkway test system. Pedestrian step frequency and step length and the dynamic load factors (DLFs) and phase angles of the first five orders of the Fourier series walking load model were also calculated. Walking load parameters of 94 test subjects aere analyzed. Step frequency and step length approximately followed normal distribution respectively. Linear regression models concerning step frequency are proposed for the first five orders of DLFs. A Fourier series walking load model, considering five orders of harmonics, was developed. Comparisons with other walking load models show that the walking loads vary by the population researched, and the constructed model can reflect the walking load characteristics of Chinese people well.
