CFS with lipped and double intermediate web stiffener is selected. CFS is cut in certain height and spacing to form curved section that identified as CFS cut-curved section. CFS is separated into two samples with a variety of heights of compression member that known as CFS normal and cut-curved section. The mechanical behaviour of both samples with slender section is determined. From the observation and testing, the percentage difference between CFS normal and cut-curved is stated of 30-39%. This reduction is reasonable and practical because the reduction of ultimate load still below half of the ultimate load of CFS normal section. The web and flange deformation is determined by using transducers, noted to have the large deformation and concluded fail due to local buckling in early stage and global buckling in final stage. ER -
