A Study on the Improvement and Test on Welding Performance of R/C Column-Steel Girder Connection

철근콘크리트 기둥과 철골 보의 접합부 형식 발전 및 용접성능에 관한 시험적 연구

This research has improved composite joint system of R/C column and steel beam developed at previous study. In this system, the shear force occurred at beam is transmitted by bearing resistance of stiffness and moment is resisted by tension capacity of coupling members. As the preliminary step of stress transfer tests of this system, welding performance test of coupling member such as round bar or square bar which has a role of moment transfer has been carried out. From the test, this element has a good welding performance and enough resistance capacity compared to design force.
