Experimental Study on Flexural Capacity of One way RC Slabs Strengthened By Steel Fiber

According to the experimental study on flexural capacity of 3 steel fiber reinforced concrete(RC) slabs and a common concrete slab with size of 500 mm×100 mm×2 000 mm,the deflection curve under all levels load,load-mid span deflection curves,development of cracking and failure mode of the slabs are obtained.The results show that the cracking load,yield load,ultimate load as well as stiffness and flexural toughness of one way RC slabs strengthened by steel fiber are improved,steel fiber can effectively block the crack development;the stiffness reports three stage variation model and the failure mode is the tensile steel bar yield as same as the common RC slab.
