| Abstract |
This study is a series of experimental investigation on the buckling strengths of eccentrically compressed cold formed stainless steel CHS(circular hollow section) columns. The principal parameters in this study are slenderness ratios(λ=30, 50, 70) and magnitude of eccentricity e(0, 2.5, 5.0, 7.5, 10㎝) on the direction of end moment. The direction of end-moment means 3 different bending moment distributions. Objectives this study are to obtain the maximum loads and moments by performing an experimental work and to compare the experimental behaviors with the design standard curves, AIK-LSD and AISC-LRFD, AIJ-LSD, SIJ-ASD curves. The ultimate buckling strengths and bending moments of circular section members are evaluated by a method in accordance with design standard curves. Therefore this paper attempts design standard for the use of these stainless steel columns as structural compression members. The numerically obtained ultimate buckling strengths and bending moments design standard curves of beam columns show a reasonably good agreement with the available experimental results. |
