利用三维动作捕捉技术结合三向测力板，开展了7种不同步行频率下行走激励的动力特性实验，得到73人次5004条有效单足落步荷载曲线。利用实测的双足重合的准确时间点将单足落步荷载曲线拓展成连续时程曲线，进而得到行走激励竖向及横向分量的傅里叶级数模型的前5阶系数及相位角值。与其它国家现有模型的比较反映出了不同人群特性的差异，所建议模型可用于大跨工程结构考虑行走作用的振动舒适度问题的设计与分析。

Using a three-dimensional human motion capture system and three-dimensional force plates,a series of experiments on dynamic properties of human-induced walking load with seven different walking frequencies were conducted.73 persons participated in the experiments to acquire 5 004 record curves of single-footfall trace.The continuous time history of walking load was synthesized with single-step force curves by using the measured correct time points for two-fool-reclosing.Based on experimental measurements,the coefficients and phase angles of the first five orders of Fourier-series models for both vertical and lateral walking load components were achieved.Comparing this model with existing models of other countries,the difference among different nations'characteristics were reflected.The proposed model could be used for structural design and analysis of long-span structures considering the problems of serviceability caused by human walking.
