Abstract: According to the theoretical calculations and the test results ,the different mixture ratio of steel fiber reinforced self‐compacting concrete has been found in this paper .Based on the results of the concrete mechanics performance test ,through ANSYS finite element analysis the paper gets the results of steel fi‐ber reinforced self‐compacting concrete beams bending performance and fracture distribution with different mixing amount of fiber ,and the best mixture ratio of steel fiber reinforced self‐compacting concrete is found .It can provide a reference for the practical engineering .The calculation of model shows that the cracking load ,yielding load ,flexural toughness and structure stiffness of steel fiber reinforced self‐com‐pacting concrete beams are significantly increased compared with ordinary reinforced self‐compacting con‐crete beams .And it can be reasonably extrapolated that the actual ultimate load also be improved accord‐ingly .
