스티프너로 보강된 콘크리트충전 강관의 구조적 거동

Recently, In recognition of outstanding structural performance the use of Concrete Filled Tube(CFT) columns has been increased. Wehave developed in tow types of New CFT for broader usability which were bent to be ㄱ-Channel and plate each four unit member were welded. These New CFT of th experimental data were verified by comparing analysis methods. The effectiveness of CFT having the same cross-sectional area of regular steel tube with a load carrying capacity were comparing, according to variations in the strength of concrete and steel to structure performance of the New CFT were an analysis.
