Performance of Concrete Beams Strengthened with Hybrid NSM-FRP Systems: A Review

Main Article Content
Abstract
This article provides an overview of the study on the structural response of Near-Surface Mounted (NSM) FRP strengthened reinforced concrete beams within a hybrid reinforcement system. Although Fibre Reinforced Polymer (FRP) composites, such as CFRP and GFRP, have been extensively investigated, Basalt FRP (BFRP) is a relatively new but economically viable alternative material with high performance. This paper critically reviews the literature on bond enhancement of NSM-BFRP systems in flexural capacity, stiffness, and failure modes by internal reinforcement. A significant deficiency in the Application of these hybrid systems in NSC is also established, which lacks experimental data. The review concludes by emphasizing the need for codified design recommendations to enhance bond performance and ductility for hybrid NSM-BFRP systems.
