摘要
对在汶川里氏8.0级地震中受到损伤的四川某刚架拱桥进行了震后的加固改造。首先建立平面杆系有限元模型,分析结构的受力情况,再进行荷载试验,根据计算与荷载试验结果,确定了加固施工方案,并在工程完工后再进行一次荷载试验,以对比检验加固效果。
In the 8.0 magnitude Wenchuan earthquake in Sichuan Province by the injury to a rigid frame arch bridge reinforcement and reconstruction after the earthquake.First of all,the establishment of planar finite element model to analyze the structure of the forces and then load test,according to the calculation and the results of the load test to determine the reinforcement construction program,and then carry out a load test more to test the effect of reinforcement after the project.
