Abstract

Abstract

Based on the City Balcony project of Xiangluwan on conples street of Zhuhai City, the analysis and design of long-span curved steel-concrete composite pedestrian bridge were carried out. The human-induced vibration control method of irregular complex pedestrian bridge using multiple tuned mass dampers (MTMD) was introduced. Firstly, the refined finite element model of the whole bridge was established by using the general finite element software ANSYS. Then the construction process of the whole bridge was reasonably designed and the corresponding construction stage was defined in the finite element program to analyze the mechanical properties of the composite bridge during the whole construction process and the normal operation stage. The comfort of pedestrian bridge was analyzed by avoiding the sensitive frequency and limiting the dynamic response of the structure, and the comfort degree of the structure was evaluated according to the domestic and foreign specifications. Finally, a scheme of installing multiple tuned mass dampers for human-induced vibration control was proposed. The results showed that MTMD could effectively control the vertical vibration response of curved pedestrian bridge structure.
