Abstract

Abstract: In order to further study the proper design parameters of the adhesive anchorage for carbon fiber reinforced polymer (CFRP) cables, the Tsai-Wu failure criterion of composite material was introduced firstly, and the simulation analysis method of the adhesive anchorage for CFRP cables was proposed. Then, a parametric study on the anchorage performance indexes of adhesive anchorage for CFRP cables was conducted by use of the proposed method. The results show that the mechanical properties of the anchorage can be significantly improved by optimizing the total length of the anchor cup, the length of the straight tube section, the inclination angle of the inner cone section, the interval between CFRP bars and anchor cup, and by setting films between anchor cup and epoxy resin.

Key words: bridge engineering, carbon fiber, CFRP, anchorage, parametric study

摘要： 为了深入研究碳纤维增强树脂(CFRP)拉索黏结型锚具的合理设计参数，首先介绍了复合材料的Tsai-Wu失效准则，并在此基础上提出了关于CFRP拉索黏结型锚具的仿真分析方法。然后利用该方法对CFRP拉索黏结型锚具的锚固性能指标进行了参数分析，结果表明：通过优化锚杯总长度、直筒段长度、内锥段倾角、CFRP筋与锚杯间距，并在锚杯与环氧树脂之间全程布置薄膜，可显著改善锚具的受力性能。
