CRACK WIDTH CONTROL IN CONCRETE STRUCTURES WITH FRP REINFORCEMENT
Abstract eng: Traditional material for concrete reinforcement is steel. In recent times, non-metallic fibers (steel, glass, aramid, carbon, polyethylene and polypropylene) as dispersed short fibers (together with different structures such as yarn, chopped yarn, strings, nets, fabrics, and polymer composite material reinforcement (bars and cages)) have been intensively investigated and some of them used for construction of structures. FRP rebar stress-strain curves have almost linearly elastic behaviour. The paper presents the mechanical properties and durability of different types of FRP rebars and calculations of the required reinforcement area in connection with the crack widths limitations for GFRP and steel reinforcement.
