CFRP与钢板加固RC梁滞回性能有限元分析研究

Finite Element Analysis and Study on Hysteretic Behaviors of Reinforced Concrete Beams Strengthened with CFRP and Steel

采用ANSYS有限元分析软件,通过模拟低周反复荷载试验,分别对1根CFRP加固RC梁和1根钢板加固RC梁的抗震性能进行了探究。研究表明:建立合理的有限元分析模型,采取合理的求解策略,可以得出较好的滞回曲线图形,从而证实了钢板加固RC梁比CFRP加固的RC梁的抗震性能优良的结论。

Based on ANSYS finite element analysis software and by simulating the cyclic loading tests,the seismic performances of the RC beams strengthened with a CFRP and a steel are explored and studied respectively.The study results show that： through establishing a reasonable finite element analysis model and taking reasonable solution strategies,a better hysteresis curve graph could be drawn,thus to confirm a conclusion： the seismic performance of the RC beam strengthened with the steel is more excellent than that with the CFRP.
