In order to realize the rapid assembly of steel-concrete composite beams, high-strength bolts are used as shear connectors instead of studs. In order to study the shear performance of highstrength bolt connector, the finite element model of push out specimen was established by ABAQUS. The validity of the model was verified and the conclusion that the shear bearing capacity of highstrength bolt connector would be reduced by enlarging the bolt diameter. On this basis, the influence of concrete strength, bolt tensile strength, bolt diameter and pretension on shear bearing capacity of high strength bolt connections were analyzed. The results showed that the shear capacity of high-strength bolt connectors mainly depended on concrete strength, bolt tensile strength and bolt diameter, and is less affected by pretension. The research results have reference value for the application of high strength bolt connectors in prefabricated composite beams.
