Abstract：
Compared with the common concrete beam column joints, the steel fiber is incorporated into the plastic hinge at the end of the beam column joints, and the failure process, the crack strength, the shear strength and the shear ductility were researched. Results show that: After the steel fiber is incorporated into the plastic hinge region of the beam column joint, stiffness, crack resistance, shear strength and shear ductility are greatly improved. Finally, the seismic performance of beam column joints is improved effectively.
