In this paper,based on the mechanical capacity of beams reinforced with steel fiber in torsion and taking account of the influence of the steel fiber,the formulas on ultimate torque of the beams are given using the variable angle space truss model.So that the formulas make the function of steel fibers as the equivalent longitude and transverse steel bars,which can joint well with the calculation formulas on ultimate torque of common reinforced concrete beams.Then the prediction results are compared with the results of the test,and the calculation precision of the formulas is high,Which can be used in practice.
