桥梁振动是环境问题的主要焦点,特别是在城市软土地基地区。桥梁的结构体系对桥梁的人体工程学适用性、车辆活载引起的次声和地面振动有很大影响。本文考虑车辆活载与桥梁结构体系的相互作用,对桥梁的振动舒适度进行了研究。采用有限元分析的数值方法,对四种不同结构体系(包括桥梁的相邻引桥部分)的柔性单跨桥梁在车辆活载作用下的基本动力特性进行了理解和评估。
Bridge vibration is the major focus of environmental issues, especially in urban areas where the ground is soft. The structural system of the bridge greatly influences the ergonomic serviceability of the bridge, infrasound and ground vibration by vehicular live load. This paper discusses the vibrational serviceability of bridges, considering the interaction between vehicular live load and the structural systems of the bridge. The numerical approach with Finite Element Analysis was conducted to understand and evaluate the fundamental dynamic behaviour of flexible single span bridges under vehicular live load for four types of different structural systems, including the adjacent approach parts of the bridges.
