Analysis of Human-induced Vibration and Stability Cable of Pedestrian Suspension Bridge on the Influence of Bridge Comfort

In the context of the booming and rapid expansion of the tourism industry, an increasing number of aerial glass landscape bridges with complete transparency have been built in various scenic areas, commonly adopting the structural form of suspension bridges. Of notable concern are incidents of human-induced bridge vibrations that have occurred both domestically and internationally, causing considerable distress among tourists. Therefore, it is of paramount importance to conduct further study into the comfort of pedestrian suspension bridges. Given the above circumstances, a finite element model of the pedestrian suspension bridge is constructed, with a primary objective of simulating and analyzing the responses of tourists engaged in stationary dance, walking and running at different positions and under diverse loading conditions, while additionally exploring the effects of installing various stable cables on bridge vibration and comfort. Subsequently, the relevant conclusions are further verified through physical model experiments.
