The implications of low-ductility reinforcement and strain localisation on the strength and ductility of reinforced concrete two-way slabs. In the design of reinforced concrete structures, ductility is an important requirement, providing warning of failure, redistribution of internal actions at overloads and justification of many of the assumptions made in structural analysis and design. The recent introduction in Australia of low-ductility, deformed welded wire fabric reinforcement (Class L) ha ....The implications of low-ductility reinforcement and strain localisation on the strength and ductility of reinforced concrete two-way slabs. In the design of reinforced concrete structures, ductility is an important requirement, providing warning of failure, redistribution of internal actions at overloads and justification of many of the assumptions made in structural analysis and design. The recent introduction in Australia of low-ductility, deformed welded wire fabric reinforcement (Class L) has resulted in concrete slabs with relatively brittle failure modes and its use has been the subject of much debate. This research will investigate the ductility of two-way slabs containing Class L mesh and the applicability of established design procedures. It will lead to safer and better performing r.c. floor systems and, if necessary, new ductility specifications for Class L steel.Read moreRead less

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 ....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.Read moreRead less
