Design of Cold-Formed Unlipped Channels Subjected to Web Crippling

摘要

The report presents a series of tests on cold-formed unlipped channels subjected211u001eto web crippling. The tests were conducted under the four loading conditions 211u001especified in the Australian/New Zealand Standard (AS/NZS 4600, 1996) and the 211u001eAmerican Iron and Steel Institute (AISI, 1996) Specification for cold-formed 211u001esteel structures. The four specified loading conditions are the End-One-Flange 211u001e(EOF), Interior-One-Flange (IOF), Ent-Two-Flange (ETF) and Interior-Two-Flange 211u001e(ITF) loading. The loading of concentrated load or reaction forces were applied 211u001eby means of bearing plates which acted across the full flange widths of the 211u001echannels. The web slenderness values of the channel sections ranged from 15.3 to 211u001e45.
