摘要
本文描述了一个几何相似比为1∶18的桥梁模型结构的地震模似试验。采用铰支-滚动、橡胶和铅-橡胶等三种不同型式的支座、比较它们的地震反应和减振效果。
A earthquake simulation test of bridge model is described in this paper.The model scale ratio is 1/18 for Gaojiagou Bridge,In the test three types of bearings were used, rubber bearing,lead-rubber bearing and hinge-rolling bearing.The model was tested on 5M×5M earthquake simulation shaking table.The input excitation is El-centro NS Component.The acceleration response,relative displacement and strain of model struc- ture were measured,some available conclusions were obtained from the testing.
