The impact load performance of beam column joints is directly related to the safety and stability of prefabricated buildings.The impact load behavior of beam column joints in prefabricated steel structure comprehensive distribution room is studied.The study uses four kinds of steel as raw materials,sixteen beam column joint specimens of distribution room,and uses four different connection modes.According to the test piece,the universal testing machine is used to apply different levels of loads,and a variety of sensor equipment are used to collect data at the same time,calculate the three indexes of impact load performance,namely,ultimate bearing capacity,ultimate flexural strength and ultimate impact strength,and complete the im-pact load performance analysis of beam column joints in power distribution room.The test results show that ordinary steel,weathering steel,refractory steel beam and column with steel bar lap method are the best impact load resistance performance,high strength steel is the best full bolt connection impact load resistance performance,it can be selected according to the specific steel connection method.
