Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : This note presents an experimental study of the bearing strength of cold-formed steel (CFS) bolted connections using oversized holes without washers. The test parameters include the sheet thickness, the connection type, the number of bolts, and the bolt diameter. The test results indicate that the use of oversized holes without washers will cause excessive connection deformation and reduce the connection strength. Based on the test data, a new design method is developed to accurately determine the bearing strength of CFS bolted connections when oversized hole is used without washers.

Distortional buckling of cold-formed steel shear wall studs under uplift force / Cheng Yu in Journal of structural engineering, Vol. 136 N° 3 (Mars 2010) 

Public ISBD [article]  in Journal of structural engineering > Vol. 136 N° 3 (Mars 2010) . - pp. 317-323 Titre : Distortional buckling of cold-formed steel shear wall studs under uplift force Type de document : texte imprimé Auteurs : Cheng Yu, Auteur Année de publication : 2011 Article en page(s) : pp. 317-323 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Cold-formed  steel  Shear  wall  Distortional  buckling  Direct  strength  method Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : A cold-formed steel framed shear wall may fail in shear buckling of the sheathing, local buckling or distortional buckling of the framing member under compression forces or connection failures. An unusual distortional buckling mode on boundary studs under uplift forces was recently observed in a shear wall test program conducted at the University of North Texas. It was found in monotonic pushover shear wall tests that the flanges of the boundary studs undertaking uplift forces were distorted at the bottom area of the studs near the hold-down. This paper presents the test program and analysis of the unique distortional buckling mode. The paper also provides procedures for predicting the distortional buckling strength of the boundary studs, as well as the construction details to mitigate the damage by this unexpected distortional buckling mode.
