Abstract

Despite numerous investigations conducted in the field and the evident importance of this area of study, comprehensive reviews are still lacking, resulting in a noticeable gap in comprehension. Therefore, this paper presents an in-depth review of repair methods for heat-damaged reinforced concrete (RC) beams utilizing carbon fibre-reinforced polymer (CFRP) composites through both externally bonded reinforcement (EBR) and near-surface mounted (NSM) techniques. The paper meticulously compiles and analyses relevant experimental data, examining flexural and shear repair mechanisms, associated failure modes and factors influencing the repair processes, such as the form, length, spacing, orientation and number of CFRP reinforcement layers, as well as the type of bonding agent. Thus, this review serves as a valuable resource and guide for engineers and researchers seeking to deepen their knowledge in this field.

The review concludes with recommendations for future research directions aimed at advancing the development and application of repair technologies for heat-damaged RC members.

使用外部粘接和近表面安装的纤维增强塑料复合材料修复热损伤 RC 梁的综述

尽管在该领域进行了大量研究，而且该研究领域的重要性显而易见，但仍然缺乏全面的综述，因此在理解方面存在明显差距。因此，本文通过外部粘接加固（EBR）和近表面安装（NSM）技术，对利用碳纤维增强聚合物（CFRP）复合材料修复热损伤钢筋混凝土（RC）梁的方法进行了深入评述。论文对相关实验数据进行了细致的汇编和分析，研究了弯曲和剪切修复机制、相关失效模式以及影响修复过程的因素，如 CFRP 加固层的形式、长度、间距、方向和数量，以及粘接剂的类型。因此，本综述可作为工程师和研究人员深化该领域知识的宝贵资源和指南。综述最后提出了未来研究方向的建议，旨在推进热损伤 RC 构件修复技术的开发和应用。
