The Application of Plate Buckling Theory in the Steel Structures

Abstract:

Based on the width-to-thickness ratio of plates, four types of sections are proposed and post-buckling design, elastic design, elastic-plastic design and plastic design are employed respectively. Taking the post-buckling strength of plates into consideration, cold-formed thin-wall steel structures shall adopt calculation by effective width, also post-buckling design, and the restrain coefficient k₁ of the plate groups shall be used. The direct strength method is quite convenient but needs the finite strip method. The computation of medially stiffened plates and distortional buckling has been figured out and thus further research and supplement are necessary.
