Abstract:
This paper addresses structural performance of concrete slabs reinforced with a new type of specially shaped high-strength steel rebar. Because of its high strength and good bonding property with concrete, concrete members reinforced by the new rebar type are supposed to be of superior mechanical properties. To investigate the flexural behaviour of the specially reinforced concrete members, four one-way and one two-way slabs with a span length of 3 m (10 ft) each were tested in the structural laboratory at Tongji University, China. Experimental results verified that the slabs reinforced with special rebar type indicated higher load capacity, thinner cracks and better ductility as compared to the slabs reinforced with normal steel rebars.
