Quasi-static test is done on the prefabricated steel reinforced concrete frame joints. Then this paper analyzes the seismic index of failure forms, hysteretic behavior and energy consumption of prefabricated steel reinforced concrete frame side joints, middle joints and casting contrast joints. The research shows that the prefabricated joints have similar failure forms with the casting joints, and all the joints achieve the failure mechanism of beam end plastic hinge. Both the prefabricated steel reinforced concrete frame joints and casting contrast joints have similar seismic performance, so the prefabricated steel reinforced concrete frame joints can be designed according to standards of casting steel reinforced concrete frames in actual projects.
