| 摘 要： | 结合CFRP片材和钢筋混凝土梁的材料及工作特性，通过有限元数值模拟了CFRP加固钢筋混凝土粱的工作特性，并与试验结果进行了对比。分析结果表明通过合理选择有限元分析数值模型，可有效预测CFRP加固梁的工作性能。在此基础上，对CFRP片材加固钢筋混凝土梁的正截面受力机理进行了分析，为今后进行更深层次的数值试验和更广泛的影响因素敏感性分析奠定了基础。

| Abstract: | In this paper, by considering the material features and working rules of CFRP and reinforced concrete beam, and by using finite element method the working principles ot reinforced concrete beam strengthened with CRFP laminate was numerically simulated, and compared with experimental results. The analysis results show that by founding suitable finite element solution models, the working principles of CFRP-strengthened beam can be forecasted effectively. Based on this, the load carrying capability of CFRP-strengthened beam was analyzed, which settled a foundation for the more deeply numerical experiments and the more widely sensitivity analysis in the future. |
