Investigation of Single Span Z-Section Purlins Supporting Standing Seam Roof Systems Considering Distortional Buckling
… method for the determination of the governing buckling strength for cold-formed purlins supporting a standing seam metal roof system is the 1996 AISI Specification for the Design of Cold-Formed Steel Structural Members, which contains provisions for local and lateral buckling. Previous research …

Cold-Formed Steel Behavior: Elastic Buckling Simplified Methods for Structural Members with Edge-Stiffened Holes and Purlin Distortional Buckling Strength Under Gravity Loading
Elastic Buckling Simplified Methods for Structural Members with Edge-Stiffened Holes: Presently, the current design methods available to engineers to predict the strength of cold-formed steel members with edge-stiffened holes remains largely unaddressed in the North American Specification for the …

Experimental and Analytical Studies of the Behavior of Cold-Formed Steel Roof Truss Elements
… engineer typically tries to improve the local buckling behavior of the cold-formed steel elements. The complex hat shape has proved to limit the negative influence of local buckling, however, distortional buckling can be the controlling mode of failure in the design of chord members with …

Elastic buckling solutions for thin-walled metal columns with perforation patterns
… strip methods for use in predicting elastic buckling strength of cold-formed steel columns. These methods were developed by examining elemental behavior of cross-sections in eigen-buckling analyses and validated using a large database of finite element rack-type columns with perforation …

Effect of Thermal Loading on the Performance of Horizontally Curved I-Girder Bridges
… thermal loading leads to global and local buckling along the Igirder web centerlines, lateral distortional buckling in the web cross section, and thermal stresses in the I-girder webs. Although pier flexibility is shown to reduce the magnitude of thermally induced local and lateral …

Resistance Factor for Cold-Formed Steel Compression Members
… support a higher resistance factor for columns buckling in a distortional buckling limit state and an expansion of the current DSM prequalified limits. The results also show that DSM predicts the column capacity more accurately than the Main Specification. The test-to-predicted ratios for plain …

Experiments on Cold-Formed Steel Beams with Holes
Experimental testing and elastic buckling studies were performed on 68 C-section cold-formed steel joists with unstiffened rectangular web holes. Four Steel Stud Manufacturers Association (SSMA) cross-section types; 800S200-33, 800S200-43, 1000S162-54, and 1200S162-97, were evaluated to explore the …

Study of seismic control systems on the behaviour of industrial storage racks
… making them sensitive to global, local, and distortional buckling if overloaded. Moreover; the connections demonstrate highly nonlinear behaviours under loading. Due to the aforementioned reasons, the design of racks poses major challenges for engineers especially in seismic regions where …
