  • Abstract:
  • In cases of structural elements, it has been analysed which may have become ineffective as time goes on due to environmental exposure, steel corrosion and increased service loads, that is Reinforced concrete (RC) beams. As a result, member strengthening has taken an essential role in today's civil engineering practice. Introduction Among all the various techniques available, Fiber Reinforced Polymer (FRP) systems draw lots of attention in the recent years, and Basalt Fiber Reinforced Polymer (BFPR) an emerging innovative material with good corrosion resistance, low cost, high durability has shown itself as a potential alternative for many applications. Nevertheless, the overall effectiveness of externally bonded BFRP laminates is frequently constrained by the premature debonding at the interface between laminate and concrete surface. This issue is primarily caused by stress concentration near the laminate ends. To address this limitation, anchorage systems are introduced to enhance bonding performance and delay failure. This study presents a comprehensive review of RC beams strengthened using BFRP laminates under both anchored and unanchored conditions. The findings indicate that anchorage systems significantly improve bond behaviour, enhance load transfer, delay debonding, and increase overall strength and crack resistance. As a result, the use of anchorage systems leads to a more reliable and efficient strengthening solution.
