According to a long-span pedestrian suspension bridge, the sectional models of the human-footbridge system were proposed, and then the force measurement tests were performed to study the effects of the pedestrian density (ρ), pedestrian permutation, and wind attack angle (α) on the drag force coefficient (C_H), lift force coefficient (C_V), and pitching moment coefficient (C_M), respectively. So, it is found that: (1) with the increase of ρ, both C_H and C_V with α < −2° increase, while both C_V with α ≥ −2° and C_M with ρ ≠ 0.0 P/m² decrease. (2) when ρ > 0.2 P/m², there is a significant effect of the pedestrian permutations on C_H and C_M, while the effect of the pedestrian permutations on C_V is small. Then, the static wind forces were calculated and applied to the pedestrian suspension bridge, and the effects of ρ and pedestrian permutations on the aerostatic response were studied. So, it is found that: 1) with the increase of ρ, the aerostatic response increases; 2) the effects of the pedestrian permutations with ρ ≤ 0.5 P/m² on the aerostatic response can be ignored, while there are disadvantageous effects of the pedestrian permutations with ρ > 0.5 P/m² and larger wind-blocking area on the aerostatic response.

针对某大跨度人行悬索桥，提出了人行天桥系统的断面模型，然后进行了测力试验，研究了行人密度（ρ）、行人排列和风迎角（α ) 分别对阻力系数 ( C _H )、升力系数 ( C _V ) 和俯仰力矩系数 ( C _M ) 产生影响。所以，发现：（1）用的增加ρ，既Ç _ħ和Ç _V与α <-2°的增加，而这两种Ç _V与α ≥ -2° 和C _M与ρ ≠ 0.0 P/m ²减少。(2) 当ρ > 0.2 P/m ^{2 时}，行人排列对C _H和C _M的影响显着，而行人排列对C _V的影响较小。然后，计算静态风力并将其应用于人行悬索桥，研究了ρ和行人排列对空气静力响应的影响。所以，发现： 1) 随着ρ的增加，空气静力响应增加；2) ρ ≤ 0.5 P/m ²的行人排列对空气静力响应的影响可以忽略，而ρ > 0.5 P/m ²的行人排列和较大的挡风面积对空气静力响应的影响可以忽略不计回复。
