Investigation of a vibration mitigation method based on crowd flow control on a footbridge

The vibration mitigation method based on crowd flow control is verified by comparing the numerical and experimental results of its damping performance. pedestrian characteristics are simulated with upgraded social force model to include effects obstacles commute in a blocking scenario. coupling system’s equation established loading mass-spring-damping (MSD) structure crowd-footbridge vertical interaction analyzed. In this regard, large-span interior footbridge shopping mall was analyzed, which had been presented previous study. efficiency motion different conditions compared laboratory percentage maximum error 16.7%. mechanism described from energy perspective. were found consistent data, data simulation environment has enough reliability. It that choosing location can effectively help mitigate system. relationship between rates, number obstacles, densities statistically analyzed discuss analyses demonstrate rate directly affected specific density range. be concluded performance hybrid Layout 1 significantly more effective than 2 at high density.
