Brief description The impact of high strength, low ductility reinforcement on the ductility and serviceability of concrete structures. The behaviour of reinforced concrete structures has been adversely affected by the recent introduction in Australia of 500 MPa steel reinforcement(with higher strength and lower ductibility than the previously available 400MPa steel bars). Structures with reduced ductility, greater deflection and larger crack widths will result. Unexpected overloads may now cause fracturing of the steel, resulting in brittle and catastrophic collapse. This project aims to investigate, analytically and experimentally, the impact of the new reinforcement on the design and performance of concrete structures, including strength, ductility and serviceability, and to provide rational design guidance to the structural engineering profession.
