Building upon a previous set of experiments performed to determine connection rotational restraint provided by sheathing in cold-formed steel floor joists, this study investigates the reliability of reported connection ...

Buildings framed from cold-formed steel members are becoming increasingly common. Simulation of cold-formed steel (CFS) structures in this dissertation includes seismic modeling and analysis of a two-story CFS-framed ...

The Direct Strength Method (DSM) of cold-formed steel member design employs local, distortional, and global cross-section elastic buckling analysis with empirically derived “direct” expressions to predict member strength. ...

The experimental behavior of cold-formed steel (CFS) structures under seismic loads remains relatively unexplored. Modern design codes are based on member and sub- system level testing and have not been validated at the ...

Cold-formed steel may be used to frame the walls, floors, and roofs of modern buildings. The individual cold-formed steel members (studs) have sheathing attached to provide appropriate architectural enclosures. This sheathing ...

The enclosed research report has been prepared for the AISI as supporting material for proposed additions to the AISI Specification (AISI-S100-07) with respect to inelastic bending of cold- formed steel flexural members. ...

Laterally braced cold-formed steel beams generally fail due to local and/or distortional buckling in combination with yielding. For many cold-formed steel (CFS) studs, joists, purlins, or girts, distortional buckling may ...

This is an informal progress report document summarizing recent work on the development of a design method for sheathing braced design of wall studs with dissimilar sheathing. This document focuses on only one aspect of ...

A series of cantilever tests on joist-sheathing assemblies were conducted to determine the rotational restraint that sheathing provides to the compression flange of a floor joist in bending. This rotational restraint, which ...

This report details the work performed under a research grant funded by the American Iron and Steel Institute (AISI) and the Metal Building Manufacturers Association (MBMA) entitled “Test Verification of the Effect of ...
