The concrete-filled steel tube（CFT） column system has many advantages compared with the ordinary steel or the reinforced concrete system. One of the main advantages is the interaction between steel tube and concrete : local buckling of steel tube is delayed by the restraint of concrete, the strength of concrete is increased by the confining effect of the steel tube. Extensive research works have been done in Japan last 15 yers, including the "New Urban Housing Project" and the "US－Japan Cooperative Earthquake Research Program", in addition to the works doue by individual universities and industries that have been presented at the annunl meetings of Architectural Institute of Japan （AIJ）. Mie University has also been contributing to the development of the CFT column system in a great extent. This paper introduces the structural system and discusses advantages, rescarch findings, trial designs, and recent construction trends of CFT column system in Japan. The paper also describes the design recommendations for the design of compression members, beam-columns, and beam-to column connections in the CFT column system.
