Steel reinforced concrete special-shaped column is a new structural form. It has all priorities of steel reinforced structure and special-shaped column structure. Bearing capacity and ductility of this new structure are very good. It also has very excellent applicable quality and pleasing to the eye. But there are still few experimental and research results relevant to this new structure. The design of steel reinforced concrete special-shaped column joints is a most important problem that must be solved to ensure that this new structural could be widely used in the future. This research focuses the attention on the seismic behavior of this kind of joints, and adopts the new joint design style. The pseudo-static test is carried out on joint specimens. Hysteresis loop of all the specimens have been drawn. The energy dissipating capacities are evaluated. Based on the results of experimental research, the behavior of high resistant capacity, excellent ductility and reliability of the joint design method have been manifested. Taking into account all these facts, this article also put forward practical design suggestions on this structure.
