| Summary |
"An extensive experimental investigation has been conducted to study the load-carrying capacity of cold-formed steel web elements subjected to partial edge loading which may cause web crippling or web buckling. In this experimental work emphasis was concentrated on the cold-formed steel structural members having single unreinforced webs with stiffened flanges. In 1980, American Iron and Steel Institute (AISI) revised its "Specification for the Design of Cold-Formed Steel Structural Members" For the design of beam webs, Section 3.5.1 of the AISI Specification provides the design criteria for web crippling. This thesis discusses the experimental work including some specimens with small length-to-depth ratios which may cause web buckling rather than web crippling. The failure mode for these specimens is beyond the scope of the current AISI Specification. Based on the results of tests conducted in this study, new design expressions have been developed to determine the critical web buckling load. Recommended design criteria are proposed for cold-formed steel structural members having single unreinforced webs with stiffened flanges"--Abstract, leaf ii. |
