首先对框架柱拟静力试验进行Opensees模拟分析，并掌握重要参数取值范围，然后对一栋相似比为1：4的8层双跨混凝土框架，进行了初次振动台试验，环氧树脂注胶修复，以及再次振动台试验，然后采用Opensees对初始框架和环氧树脂加固框架进行非线性动力分析，模拟结果表明计算值与试验值幅值及位移时程波形态总体吻合较好，Opensees纤维单元模型可以对不同水准地震作用下的初始框架模型和环氧树脂加固框架模型进行较为准确的模拟。

In this paper , the frame column quasi -static test was simulated and analyzed based on Opens-ees, and the range of the important parameters was grasped .Then 1:4-scale eight-story double -span rein-forced concrete frame was damaged on shaking table at first , then repaired using epoxy injection technique , at last subjected to the shaking table test again .The nonlinear dynamic characteristics of the initial frame and the frame repaired with epoxy resin injection technique was analyzed based on Opensees .The simulation results show that the magnitude and the form of displacement time histories wave of the calculated and experimental values have good agreement .The Opensees fibers element model is capable of simulating and analyzing the initial frame and the frame repaired with epoxy resin injection technique accurately under earthquake action of different levels .
