The shear tests of steel fiber high strength and high performance reinforced concrete beams are taken. The effects of the concrete strength grades, steel fiber contents and stirrups on shear capacity of the beams are analyzed. The results show that the shear capacity of the reinforced concrete beam is improved by increasing the concrete strength grade and adding steel fiber, the stirrups are involved in the shear resistance of the beams absolutely. Based on the experimental data of steel fiber highstrength reinforced concrete beams with stirrups and without stirrups tested at home and abroad, the experience formula of shear capacity of steel fiber high strength and high performance reinforced concrete beams is proposed and verified. The calculated results agree well with experimental ones.
