| Abstract: | A newly developed reinforced concrete(RC)beam to concrete-filled-steel-tube(CFST)column joint without welding in construction field is introduced in this paper.The seismic experiment is conducted on the joint,and the hysteretic curve of the specimen under cyclic loading on column top is obtained.According to the test results,this joint shows good ductility and the ability of energy dissipation,and it can be used to replace the joints with welded reinforcement on the outer annular plate.Moreover,the test is also simulated with FEM,and the results agree well with the skeleton curves obtained from the test.Parametric analysis is conducted on this joint,with the consideration of different design of beam,column and steel bracket,and the failure mode is discussed. |
