RISLocal-Plate and Distortional Postbuckling Behavior of Cold-Formed Steel Lipped Channel Columns with Intermediate Stiffeners
Publisher: American Society of Civil Engineers
Abstract: This paper reports a detailed investigation concerning the local-plate and distortional elastic postbuckling behaviors of cold-formed steel lipped channel columns with web and flange intermediate stiffeners (the corresponding ...
Elastic Bifurcation, Postbuckling Behavior, and Collapse of Thin-Walled Regular Polygonal Columns
Publisher: American Society of Civil Engineers
Abstract: This paper summarizes recent findings concerning the elastic bifurcation and postbuckling behaviors of thin-walled regular convex polygonal tubes subjected to uniform compression. Such cross sections exhibit rotational ...

Proposal to Improve the DSM Design of Cold-Formed Steel Angle Columns: Need, Background, Quality Assessment, and Illustration
Publisher: American Society of Civil Engineers
Abstract: This paper presents a proposal for the codification of an efficient design approach based on the direct strength method (DSM) for cold-formed steel equal-leg angle columns with short-to-intermediate lengths, i.e., those ...
Behavior, Failure, and Direct Strength Method Design of Steel Angle Columns: Geometrical Simplicity versus Structural Complexity
Publisher: ASCE
Abstract: This work provides a state-of-the-art report on the current knowledge concerning the structural behavior and design, by means of the Direct Strength Method (DSM), of steel equal-leg angle columns with short-to-intermediate ...
Lateral-Torsional Stability Boundaries for Polygonally Depth-Tapered Strip Cantilevers Under Multi-Parameter Point Load Systems—An Analytical Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports an analytical study on the elastic lateral-torsional buckling behavior of strip cantilevers (i) whose depth is given by a monotonically decreasing polygonal function of the ...
Flexural-Torsional Buckling of Cantilever Strip Beam-Columns with Linearly Varying Depth
Publisher: American Society of Civil Engineers
Abstract: In this paper, one investigates the elastic flexural-torsional buckling of linearly tapered cantilever strip beam-columns acted by axial and transversal point loads applied at the tip. For prismatic and wedge-shaped members, ...
