用于加固混凝土结构的纤维增强聚合物（FRP）系统是传统加固技术（如钢板粘结、截面扩大和外部后张）的替代方案。FRP加固系统使用FRP复合材料作为外部粘结或近表面安装钢筋的补充。与传统加固技术相比，FRP系统具有以下优点:重量轻，相对容易安装，且无腐蚀性。由于FRP材料的特性以及FRP加固构件的性能，需要对这些系统的使用提供具体指导。 本指南提供了FRP加固系统的历史和使用的一般信息；FRP材料特性说明；以及用于加固混凝土结构的FRP系统的工程、施工和检查建议。本指南基于从用于加固混凝土结构的FRP系统的实验研究、分析工作和现场应用中获得的知识。

Fiber-reinforced polymer (FRP) systems for strengthening concrete structures are an alternative to traditional strengthening techniques such as steel plate bonding, section enlargement, and external post-tensioning. FRP strengthening systems use FRP composite materials as supplemental externally-bonded or near-surface-mounted reinforcement. FRP systems offer advantages over traditional strengthening techniques: they are lightweight, relatively easy to install, and noncorroding. Due to the characteristics of FRP materials as well as the behavior of members strengthened with FRP, specific guidance on the use of these systems is needed. This guide offers general information on the history and use of FRP strengthening systems; a description of the material properties of FRP; and recommendations on the engineering, construction, and inspection of FRP systems used to strengthen concrete structures. This guide is based on the knowledge gained from experimental research, analytical work, and field applications of FRP systems used to strengthen concrete structures.
