摘要
本文采用ANSYS有限元分析软件模拟低周反复荷载试验,分别对两根CFRP加固RC梁和一根普通RC梁的滞回性能进行了分析,然后分别与试验所得滞回曲线进行对比;研究表明:有限元分析结果与试验结果吻合较好,能够证明普通混凝土梁的滞回环较加固梁要饱满,耗能面积大,但承载力比加固梁则偏低。
This article used ihe finite element analysis software ANsYs to simulate the low cyclic loading.The hysteretic behavior between two CFRP strengthened RC beams and a common RC beam was analyzed respectively.Then the results were compared with the income hysteretic curve.It showed that the finite element analysis was accordance with the experimental results,which proved that the bearing capacity of CFRP reinforced beam was better than the normal concrete beam.
