Computational modeling of cold-formed steel: characterizing geometric imperfections and residual stresses
Benjamin W. Schafer,Teoman Peköz +1 more
TL;DR: In this paper, a preliminary set of guidelines for computational modeling of imperfections and residual stresses of cold-formed steel members is presented, based on simple rules of thumb and probabilistic concepts for characterization of both quantities.
Journal ArticleDOI
Review: the direct strength method of cold-formed steel member design
TL;DR: A review of the development and current progress in the Direct Strength Method for cold-formed steel member design is provided in this paper, where a brief comparison of the direct strength method with the Effective Width Method is provided.
Journal ArticleDOI
Local, Distortional, and Euler Buckling of Thin-Walled Columns
TL;DR: In this paper, a closed-form prediction of the buckling stress in the local mode, including interaction of the connected elements, and the distortional mode including consideration of the elastic and geometric stiffness at the web/flange juncture, is provided and shown to agree well with numerical methods.
Buckling Analysis of Cold-formed Steel Members with General Boundary Conditions Using CUFSM Conventional and Constrained Finite Strip Methods
Zhanjie Li,Benjamin W. Schafer +1 more
TL;DR: The objective of this paper is to provide the theoretical background and illustrative examples for elastic buckling analysis of cold-formed steel members with general boundary conditions as implemented in the forthcoming update to CUFSM.
Journal ArticleDOI
Steel foam for structures: A review of applications, manufacturing and material properties
TL;DR: A review of the structural application, manufacturing, material properties, and modeling of a new material: steel foam is provided in this article, where the authors highlight the potential of steel foams for use in civil/structural applications.
