| Abstract |
This study is a series of experimental investigation on the buckling strengths of eccentrically compressed cold-formed stainless steel square 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 symmetrical end-moment. Objectives this paper are to obtain the maximum loads by performing an experimental work and to compare the experimental behaviors with analytical results. The ultimate buckling strength of square section members are evaluated by a numerical method in accordance with the bending moment-axial force(M-P) interaction curves. The behavior of each specimen is displayed in the form of moment-angle(M-θ) relationship. The numerically obtained ultimate buckling interaction curves of beam-columns show a reasonably good agreement with the available experimental results. |
