| Abstract: | A theoretical study of post-buckling strength of the plate with initial imperfections based on large deflection theory is ptesented. In this paper, a B-cubic spline function semianalysis method applicable for various kinds of loading and boundary conditions is used. The advantages of the presented method as compared with ordinary finite element method are its high accuracy and economy in Saving computer storage and time. The results of the study may be useful in the design of cold-formed steel structures. |
