Abstract:
Using steel fibres for primary reinforcement in structural elements requires design methods based on meaningful material properties and good construction practices. In recent years, worldwide research efforts have brought the knowledge on these two aspects to a level which allows steel fibres to be considered for primary reinforcement for structural applications. Experiences in Canada have shown that using steel fibres in bridge deck design is a sound and economical solution that can solve several issues related to conventional reinforced concrete (R/C) design. This paper presents the proposed solution for bridge deck design in which SFRC is considered for primary reinforcement. It describes the concept and the main steps of the research program that supported its development. The performance of the proposed approach is shown in service and ultimate conditions. The design of a real bridge deck with reduced reinforcement illustrates the application of a proposed simplified design method. Recommendations for designing bridge elements made with SFRC are suggested.
