In order to respond to the call of the strategy to vigorously carry out the fabricated structure, a new lateral connection joint-prefabricated steel joint with grouting bolt sleeve, which is adopted in the prefabricated steel reinforced concrete shear wall structure. Through uniaxial tensile test and finite element analysis, the prefabricated steel joint is comprehensive analysed, to get the impact trend of the anchorage length, sleeve wall thickness, bolt diameter to the connection performance, to determine the practicability and reliability of the connection way, and to ensure connection performance in the prefabricated steel reinforced concrete shear wall structure system. With the comparative studies, we find that, the finite element analysis and test results have high fitting degree, and can be verificated each other; the bolt diameter, sleeve wall thickness and anchor length all have positive effect trend on the tensile properties of the joint, but the influence decreases; The bolt diameter should be more than 12mm, the sleeve wall thickness should be more than 5mm, and the anchorage length should be more than 70mm; the shear bond diameter can reduce the diameter, and can change the section setting to the ring setting; the comparative results can provide reliable data support for the prefabricated steel connection joint design.
