Abstract: A configuration method of 3.0% volume quantities of steel fiber reinforced self-compacting concrete has been got through continuous trial mixture in this study. Based on the concrete mechanics performance tests，the mechanical properties of concrete index under various mixing ratios are obtained. According to the measured material properties, the testing beams are simulated using ANSYS finite element software . The calculation results show that the cracking load, yielding load, flexural toughness and structure stiffness of 3.0% volume quantities of the steel fiber reinforced self-compacting concrete beam, compared with ordinary reinforced self-compacting concrete beams, are significantly increased. It is found that the anti-crack function of the steel fiber is obvious by comparative analysis of two groups of testing beams in the change law of the crack width changing with the load and the same cross section at different heights of concrete strain distribution. It can also effectively improve the ultimate tensile strain of concrete. The analysis results can provide a reference for the similar research projects.
