摘要

本文回顾了最近关于钢筋混凝土（RC）结构部件的研究，例如梁柱接头（BCJ）。这些构件采用无腐蚀形
状记忆合金（SMA）、纤维增强聚合物（FRP）或这两种材料的组合进行内部或外部增强。粘合 FRP板或近表面贴
装（NSM）FRP钢筋用于外部加固案例。在RC结构中使用 FRP和 SMA材料可以提供巨大的潜在好处，包括RC结
构的终身成本节约、耐用性、安全性和震后可维修性。尽管 FRP材料以其耐腐蚀性、高强度重量比、易于应用和可
施工性而闻名；作为增强材料的 SMA材料允许结构在负载终止后恢复其原始形状，而不会产生任何永久性大残余变
形。总之，所提出的文献综述提供了对使用这些材料进行改造或加固RC结构部件的正在进行的研究以及该领域未
来研究的趋势的洞察。还讨论了成本和耐用性。
