摘要

An experimental campaign on a full-scale steel-fibre-reinforced concrete (SFRC) flat slab of 70kg/m~3 was performed in order to investigate the design methods recently published by fib in the Model Code for Concrete Structures 2010 (MC2010). These experiments were based on uniformly distributed loadings as well as concentrated loadings. By using the concrete's characterization on small specimens, the ultimate flexural load-bearing capacity of the slab was checked according to the relationships given in the MC2010 with a full plastic approach. The tests confirm the ductile behaviour and the redundancy potential of SFRC in flat slabs. Identification of the worst yield lines pattern remains an important task for the designer as it significantly influences the result. Structural design supported by the yield line theory and laboratory characterization based on three-point bending tests provides a rather conservative result for comparison with the observations of the full-scale test.
