Analytical Study on Rotational Restraint of Sheathing
(2008)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 ... -
Behavior and Design of Sheathed Cold-Formed Steel Stud Walls under Compression
(2011)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 ... -
Behavior of Full-Scale Cold-Formed Steel Buildings under Seismic Excitations
(2014)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 ... -
CFS-NEES Building Structural Design Narrative
(2011)The NSF sponsored CFS-NEES1 project R-CR: Enabling Performance-Based Seismic Design of Multi-Story Cold-Formed Steel Structures project was undertaken to study the behavior, particularly seismic behavior, of light-framed ... -
Characterizing the load-deformation behavior of steel deck diaphragms using past test data
(2017-06)Recent research has identified that current code level seismic demands used for diaphragm design are considerably lower than demands in real structures during a seismic event. However, historical data has shown that steel ... -
Cold-Formed Steel Gravity Walls with Bridging and/or Sheathing
(2020-01)The objective of this report is describe experiments conducted on cold-formed steel walls under axial loading with a variety of different bracing conditions. Cold-formed steel wall systems are commonly braced using small ... -

Distortional Buckling of Cold-Formed Steel Members in Bending
(2005)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 ... -
Experimental Study on the in-plane behavior of standing seam roof assembly and its use in lateral bracing of rafters
(2020-01)The standing seam roof (SSR) system is the most commonly used roof system for metal buildings due to its superior durability, water tightness, and energy efficiency. In this type of system, SSR panels attach to Z-shaped ... -
Experiments on Rotational Restraint of Sheathing
(2007)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 ... -
