In recent years, circular cross-sectional structural elements have widely been used as columns for buildings. In order to predict the collapse mechanism of cold-formed circular tubes analytically, their mechanical properties and mechanical behavior need to be clarified. The authors have clarified else where 1), the cross-sectional deformation mode of cold-formed circular tubes before and after local buckling subjected to pure bending. In this paper, the experimental results have been evaluated by statistical evaluation method proposed by Ochi and Kurobane and Kato, and also a comparative study of the experimental results have been carried-out. Furthermore, the local buckling behavior of four types of cold-formed circular tubes subjected to cyclic bending and shear have been examined. Finally, for the recommendation of a new structural analytical method, the cross-sectional deformation mode for the arbitrary story deformation angle of cold-formed circular columns have been clarified.
