Background
The pedestrian suspension bridge has the characteristics of strong spanning capability, attractive line shape, convenient construction and the like, and becomes a main form for constructing a large-span bridge in tourist attraction, canyon mountain areas and the like in recent years. The pedestrian suspension bridge also has the characteristics of large span, narrow bridge deck, small beam rigidity and the like, the structure is often twisted or transversely unstable under the action of wind load, and the problem of wind resistance is often the most important problem in the structural design. The 'wind-resistant cable arrangement form' study on influence analysis of static wind stability of pedestrian suspension bridges by the author of our thinking space and the Hu soldiers in 'wind-resistant cable arrangement form' published in volume 44 and 6 in 12 months in 2019 shows that the most common and economic and effective method for improving the wind resistance of pedestrian suspension bridges is to arrange a wind-resistant cable system, and the limit of the pedestrian suspension bridges on the lateral displacement of the structure after being provided with wind-resistant cables is very obvious.

The working principle of the connection form is that the tightness of the steel wire rope lantern ring is adjusted by the rope clamp, so that the wind-resistant main cable forms a hoop effect, and the position of the wind-resistant inhaul cable on the wind-resistant main cable is fixed by the friction force between the wind-resistant main cable and the wind-resistant inhaul cable lantern ring, so that the anchoring connection between the wind-resistant main cable and the wind-resistant inhaul cable is formed. However, the use effect of the connection mode in practical engineering is not ideal, because the wind-resistant guy cable and the wind-resistant main cable are not arranged vertically, the wind-resistant guy cable has component force in the tangential direction of the wind-resistant main cable, and because the contact area between the lantern ring of the wind-resistant guy cable and the wind-resistant main cable is small, the friction force between the lantern ring of the wind-resistant guy cable and the wind-resistant main cable is small, the wind-resistant guy cable is promoted to slide on the wind-resistant main cable and deviate from the designed position, so that the wind-resistant cable system cannot work linearly according to the specified design, the working efficiency of the wind-resistant cable is greatly reduced, the wind-resistant performance of the pedestrian suspension bridge is reduced, and the influence is particularly obvious in the large-span pedestrian suspension bridge.
