| Abstract: | The assistant loading unit with rigid-frame and the axial-tensile specimen with changing section and imbedding steel bars at ends are developed,the tests with normal test machine have been carried out to study the axial-tensile stress-strain curves of steel fiber reinforced concrete. The effects of the characteristic value of content and the type of steel fiber on the axial-tensile strength and the full stress-strain curve of steel fiber reinforced concrete are studied. The formulas for calculating the axial-tensile strength and the full stress-strain curve of steel fiber reinforced concrete are proposed. It applies some valuable references for the engineering application. |
