Owing to the high strength properties and the excellent in-service and physical characteristics of Fibre Reinforced Polymer (FRP) materials have potential application as reinforcement in concrete structures. When FRPs used as internal reinforcement in concrete, mostly the Carbon Fibre Reinforced Polymer (CFRP) are used since the long-term performance of Glass Fibre Reinforced Polymer (GRFP) under some environment conditions, such as exposure to high alkalinity, seawater, or deicing salts, remains unknown. Since CFRPs are more expensive than GFRP, the currently used reinforcement systems in the form of FRP bars are not structurally and economically feasible. This project proposes to make use of strength/strain capacities, and the geometric flexibilities of FRP before curing with resin to develop innovative, structurally efficient combined flexural and shear reinforcement systems in structurally optimal, concrete structures. Unlike the existing FRP internal reinforcement systems in concrete, which are largely made from unidirectional FRPs and are prone to brittle FRP/bond failures, we will use multi-directional FRP to form 3D geometries of reinforcement. The proposed research will encompass a combined experimental, analytical and numerical investigation in order to provide the knowledge required to design efficient GFRP reinforcements in structurally efficient, low embodied energy concrete structures.
