| Abstract: | The mechanical behavior of steel fibre reinforced concrete in tension,compression and bending is studied analytically and experimentally. Based on the stress-strain relationship and the assumptions proposed in this paper, the complete moment-curvature curves as well as the load-deflection curves of steel fibre and bar reinforced concrete beams in pure bending have been determined, which agree well with the test results. The equivalent stress block parameters obtained at various stages of loading show an interesting result that the position of line of the total tensile force at all loading stages seems to be independent of the fibre content, which may simplify computations in the design of steel fibre reinforced concrete members. |
