Considering the Effect of the Residual Stress, the Calculation of Whole Stability of Compression Member of Cold-formed Thin-walled Steel

摘要

By means of theoretical analysis along with experiments, this paper aims to propose a calculation method of whole stability of axially loaded compression member of hat-shaped section of cold- formed thin-walled steel ultimate load criterion on basis of the ultimate load criterion when both the cold-formed residual stress and the initial out-of straightness are considered.
