摘要：
Taking the Jiufengshan suspension footbridge as the observation site，the measured data of 2 236 pedestrian samples were obtained by video recording and manual screening，and then the distribution characteristics and statistical values of pedestrian walking parameters（step frequency，step length，and walking speed）on the suspension footbridge were statistically obtained. Moreover，the relations among step frequency，step length，and walking speed were also proposed. The conclusions are as follows. 1）On the suspension footbridge，the walking parameters of all pedestrians obey the normal distribution，i.e. step frequency~N（1.726，0.258）Hz，step length~N （0.596，0.094）m，and walking speed~N（1.013，0.260）m/s，and their rationality is also verified in some engineering applications；2） the mean values （standard deviations） of walking parameters on the suspension footbridge are less（greater）than the mean values（standard deviations）of walking parameters obtained from other walking environments；3）the mean values（standard deviations）of Chinese step frequency and length are less （greater）than that of Westerners. Therefore，in the design of suspension footbridges in China，the statistical values of walking parameters of other races and walking environments cannot be directly used，while the walking parameters suitable for suspension footbridges should be used. © 2024 Hunan University.
