The details and the basic mechanical properties of the steel tube confined concrete column and reinforced concrete ring beam joint are introduced. Test results of 37 joint models and one full scale joint under monotonic increased loading as well as test results of 14 joint models under cyclic lateral loading are presented. The experimental results indicate that the proper designed ring beam joint can transfer the frame beam shear and moment effectively and the joint has excellent deformation capacity and energy dissipation capacity.The earthquake resistance design concept of strong connection and weak member can be achievecl.The design method and the application of the joint are briefly introduced.
