The typical walking model applied on structures is the Fourier series force model, the most important parameter in the model is the dynamic load factor (DLF) which is the basis for this most common model of perfectly periodic human-induced force. Based on Fourier decomposition, many researchers have tried to quantify DLFs, but the existing factors are not suitable for low or high walking frequency, as the more and more load need to be considered in the structural calculation nowadays, the application range of DLFs need to be extended. Based on the single foot force model, this study recalculated the dynamic load factors and expanded the applied frequency range to both low and high frequencies using numerical simulation method, compared the human induced load force model of different walking frequencies. The calculated DLFs in low and high frequency obtained from this study are useful for the following analysis of structural response under more kinds of pedestrian load.
