Motor Vehicle Traffic-Induced Vibration Characteristics of the Ground and Urban Pedestrian Overpass

Abstract:

Since the 21st century, Beijing accelerate the process of internationalization. The level of the construction of Beijing city also faced a new challenge. The city traffic problems in Beijing is badly in need of improving. The stiffness of pedestrian bridge is so low that produce large vibration in the influence of ground traffic, which has a psychological effect on the pedestrian, even may cause psychological panic, anxiety and other adverse reactions. This study by monitoring the footbridge vibration at Beijing City Garden Road ,establishing finite element model to know about its severity under Motor vehicle traffic loads to get Vibration mechanics parameters. Use ISO, UK, Japan bridge design specifications and standard to check to make a scientific and reasonable evaluation on the vibration comfort about it.
