A concrete-filled tube(CFT) is n material with excellent performance resultingfrom the confined effect ofsteel with concrete and high design versatility and is being employed in more constructions recently.However,designing and processingthe bearn to column connection with CFT is difficult too.Therefore,a steel tubemembers with diaphragms(NS column)has been developed as an intermediatepart member in which the diaphragms required for the beam to column connection arefitted to the designatedpositions.This tube members with diaphragms has already obtained the general approval This report summarizes the steel tube column withdiaphragms and the performance research resultsfor the.iotnt to the actualscalethat Was conducted prior to devetoeing.
