Load-Carrying Capacity of Cold-Formed Steel Columns with Complicated Section under Eccentric Compression Loading
This paper studied 30 cold-formed steel columns with three different sections and eleven different eccentricities under eccentric compression loading by nonlinear finite element analysis using program ANSYS. Effects of the above parameters on ultimate load-carrying capacity, buckling modes, the distribution of stress and strain, and deflection behavior of channels with complex edge stiffeners under eccentric compression loading were investigated. The result shows that influence of the effective centroid offset on carrying capacity under eccentric compression loading can not be ignored. The maximum of ultimate load-carrying capacity appeared when effective eccentricity was 0 mm, and decreased with the increase of the value of effective eccentricity. Sections influence on load-carrying capacity under negative eccentric compression loading. Web stiffening can improve load-carrying capacity which the eccentricity near the web side. Sections influence on buckling modes. web stiffening can effectively avoid local buckling.
