Abstract

An experimental investigation of web crippling strength was conducted on cold- formed steel structural members. The investigation focused on the effects of overhang length on the web crippling capacity of cold-formed steel members loaded under end- one-flange conditions. The investigation was conducted in order to develop a modification to the AISI specification (2001). The AISI specification (2001) does not provide for an increase in web crippling capacity for end-one-flange loading as a result of an overhang beyond the support.

The test specimens used for the investigation were single web C-sections and Z- sections constructed in a box beam formation. The specimens were subjected to a concentrated load with support reactions positioned to satisfy AISI requirements for end- one-flange loading. The current design requirements for end-one-flange web crippling capacity were found to be conservative for overhang lengths ranging from 0.5h to 1.5h. Therefore, test results allowed for the formation of a modification factor based on h/t ratio and support overhang length"--Abstract, page iii.
