"An extensive experimental investigation has been conducted to study the load-carrying capacity of cold-formed steel web elements subjected to bending stress, shear stress, and a combination of bending and shear stresses. Emphasis has been concentrated on the instability and postbuckling strength of beam webs.
In the study of beam webs subjected only to bending, the postbuckling strength of web elements and the effect of the compression flange on the moment capacity have been carefully evaluated for beams having stiffened and unstiffened flanges. Based on 84 test results, formulas have been developed to predict the ultimate moment capacity of cold-formed steel beams with due consideration given to the actual bending strength of web elements. These formulas are based on either the full web area or the effective web area.
For a study of beam webs subjected primarily to shear, the results of 43 tests have been compared with the theoretical failure stress. It was found that the ultimate shear strength of cold-formed steel beam webs is affected significantly by the loading and support conditions.
The structural behavior of cold-formed steel web elements subjected to combined bending and shear was also investigated. Interaction formulas have been developed to calculate the ultimate capacity of web elements with due consideration given to the postbuckling strengths for both bending and shear"--Abstract, page iii.
