The behaviors of restrainers of bridges under earthquake were discussed in this thesis. To understand the relative displacement between the superstructure, a shaking table tests of a scale-down simple supported bridge were performed.

中文摘要:本研究计画於国家地震中心以一座双跨缩尺桥梁作震动台实验,观察桥梁加装防落拉杆前后及不同数量、不同尺寸的钢棒及厚度不同之橡胶垫片装设时之差异,针对防落拉杆限制两相邻桥面版相对位移量做研究探讨,并且收集结构分析软体(SAP2000)中所需设定之参数。

To resolve the design difficulties caused by small cross-section, low height of the bridge structure, the key technique problem to the bridge structure should be carried on research and analysis, such as whole calculation model, considering foundation combined action , the reasonable rigidity match to the joint of the girder and pier ,inner force redistribution caused by the system conversion ,the forecast to long-term deformation after building , stress analysis and tectonic steel bar of the anchored serration block , the influence of foundation settlement and anti- earthquake measures . To acquire feasible and reasonable technique parameters and provide the full design basis, according to analytical results adjust and optimize the bridge structure design.
