A new steel column and ready-made pile joint system is proposed by the authors. This new joint system has been using mortal in-filled steel tube joint. These abilities can enable to reduce costs and construction period by omitting mold construction work, rebar construction, and concrete work for building the foundation.
In a structural design according to the present joint system, evaluation method of ultimate strength for mortar-filled joints should be clear. Therefore, in this paper, ultimate strength evaluation method in the case of the development of pile head joint by mortal in-filled method is clarified obtained by the present experiments.
