摘要/Abstract

摘要： 对CFRP筋材锚固系统力学性能的研究进展进行了综述。重点介绍了近几年该领域的研究成果,其中包括试验研究和数值仿真研究。对当前研究进展进行了评述并给出了一些观点:指出夹片锚不能充分发挥CFRP筋材的强度,提出建立逐渐损伤强度分析方法,对夹片部位筋材的逐渐损伤破坏过程与强度进行分析预测;为了加速推广CFRP筋材的工程应用,需要对CFRP筋锚固系统的疲劳性能与应力松弛性能开展深入研究;提出了一种新型CFRP拉索结构,更有利于CFRP拉索的锚固与盘卷。最后对CFRP拉索在应用中有待于解决的一些问题进行了展望。

Abstract: A review of studies on the mechanical properties of anchorage system for CFRP cables is given in this paper. The emphasis is placed on the recent achievements in this field, in which the experimental and numerical simulation investigations into anchorage system are included. Important developments in this field are discussed. The strength of CFRP tendon can′t be into full play in wedge-type anchorage, and a progressive damage method of predicting the strength of wedge-type anchorage system should be established by using the finite element method. In order to accelerate the engineering application of CFRP tendon, the fatigue characteristics and stress relaxation of anchorage system for CFRP tendons must be further studied. A new structure of CFRP stay cable was proposed, which was advantageous to anchorage and application. In the end, the prospects of some essential areas to be researched on CFRP cables are previewed.

Key words: carbon fiber reinforced polymer tendon, anchorage system, numerical analysis, fatigue characteristics, stay cable design
