"Experimental studies were performed to investigate the possible increase in the web crippling strength of cold-formed steel members when the flanges of the members were fastened to supports as opposed to member's flanges unfastened to supports. In this study channels, I-Sections, Z-Sections, long span roof decks (hat sections) and floor decks were investigated under two types of loading conditions, End-one-flange loading (EOF) and Interior-one-flange loading (IOF).

The primary 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 these members, since the equations do not distinguish between fastened flanges and unfastened flanges.

A review of past research concerning web-crippling strength of cold-formed steel members was performed and is discussed. The current design criteria of the 1986 AISI Specification and the 1986 Automotive Steel Design Manual regarding web crippling strength of cold-formed steel members is also discussed.

Due to the fact that this was a pilot study, the number of tests performed for each type of member were limited. Therefore, there were no new equations developed, but based on the results some recommendations are made for future study"--Abstract, page iii.
