A concrete-filled tube (CFT) is a material with excellent performance resulting from the confined effect of steel with concrete and high design versatility and is being employed in more constructions recently. However, designing and processing the beam to column connection with CFT is difficult tool. Therefore, a steel tube members with diaphragms (NS colume) has been developed as an intermediate part member in which the diaphragems required for the beam to column connection are fitted to the designated positions. This tube members with diaphragms has already obtained the general approval.
