Abstract
"The purpose of this experimental and analytical study was to explore the web crippling behavior of cold-formed steel Z-sections subjected to an end one-flange loading (EOF) condition and I-sections subjected to an interior one-flange loading (IOF) condition. This study focused only on the EOF loading condition of Z-sections to further study the web crippling capacity of the Z-section members with their flanges fastened to the support. This study also focused only on the IOF loading condition of back-to-back C-sections that form I-sections. The IOF study addressed the affect of different bolt configurations used to inter-connect the C-sections. The emphasis of this investigation was to determine if the current design criteria provided by the 1986 AISI Specification was underestimating the web crippling strength of the Z-sections with their flanges fastened to supports, since the flange restraining effect is not considered in the current specification.
A review of past research conducted on web crippling strength of cold-formed steel members was performed and is discussed. Following this analytical study, an experimental investigation was conducted. The data obtained was evaluated and a statistical analysis was made to determine the best existing design approach to use for determining web crippling strength of cold-formed steel members under the above loading conditions. The research findings were used to develop suggested design modifications for web crippling strength of fastened flange Z-sections subjected to an EOF loading condition"--Abstract, p. iii
