Abstract

Fibre reinforced polymer (FRP) composite is a useful material. It has been utilised to enhance the structural behaviour of reinforced concrete beams (RCB). It is also crucial to summarise the impact of FRP on various types of RCB properties. This study summarises the FRP usage's impact on the RCB's structural behaviour based on previous research by reviewing and discussing the experimental study and finite element analysis (FEA) results. Based on previous relevant literature reviews, the experimental investigation and FEA showed significant improvements in flexure, stiffness, young modulus, load-deflection, ultimate load capacity, fracture pattern, and failure mode when FRP was used in RCB production. This FRP composite material can be used as the external reinforcement for RCB due to its high strength capability, force, load, and corrosion resistance with adhesive and anchorage properties. Using FRP in RCB can benefit civil engineering by increasing its structural behaviour and performance, especially in construction industry.

摘要

纤维增强聚合物（FRP）复合材料是一种有用的材料。它已被用于增强钢筋混凝土梁（RCB）的结构性能。总结FRP对各种类型RCB性能的影响也至关重要。本研究通过回顾和讨论实验研究及有限元分析（FEA）结果，基于先前的研究总结了FRP的使用对RCB结构性能的影响。基于先前的相关文献综述，实验研究和FEA表明，在RCB生产中使用FRP时，其在弯曲、刚度、杨氏模量、荷载-挠度、极限荷载能力、断裂模式和破坏模式方面有显著改善。这种FRP复合材料因其高强度性能、力、荷载以及具有粘结和锚固性能的耐腐蚀性能，可作为RCB的外部增强材料。在RCB中使用FRP可以通过提高其结构性能和性能，特别是在建筑行业，从而使土木工程受益。
