英文摘要	Human induced vibration of long-span beam and slab structures is a common problem in modern floor system. In order to accurately evaluate the vibration characteristics of long-span soft structures, a reasonable walking load model should be selected. Based on IPM, RFM and SMM, the pedestrian step frequency, average step speed, first-order dynamic load factor and centroid trajectory were obtained through a large number of simulations. Compared with the previous research results, the accurate input parameters of the three models were obtained. The results show that the IPM and RFM can better reflect the human gait process and centroid trajectory, and the range of accurate input parameters is wide, which can be used to study the human-structure vertical interaction. The SMM can perfectly copy the gait process and centroid trajectory. The time history curves of walking force are also consistent with the experimental results. Because the real input parameters are narrow, it cannot accurately evaluate the vibration characteristics of the structure. The IPM and RFM provide a reference for the establishment of biological force model considering pedestrian structure interaction under flexible structure. © 2020, Editorial Office of Journal of Building Structures.
