碳纤维布加固混凝土T形梁试验及有限元分析

EXPERIMENTS AND FINITE ELEMENT ANALYSIS ON BENDING PROPERTY OF RC T-BEAMS STRENGTHENED BY CFRP

在碳纤维布加固桥梁用钢筋混凝土 T 形梁抗弯试验的基础上,应用有限元方法对其进行了力学性能分析,并与试验结果进行了对比,有限元计算结果与试验结果具有较好的一致性,能很好地预测并模拟碳纤维布加固混凝土梁的抗弯性能,为以后的数值研究工作奠定了基础。

Based on the experiments of the bending behavior of simply supported RC T-beams strengthened by CFRP, nonlinear finite element analysis is presented on the mechanics performances in the ANSYS software environment, the finite element analysis results are better consistent with the test results, the flexural strengthening of carbon fiber reinforced concrete beams can be forecasted and simulated accurately on the basis of reasonable finite element numerical model , the numerical research work may be a reference for further research.
