This paper presents a series of tests carried out on cold-formed high strength steel tubular sections undergoing web crippling. The tests were conducted on square and rectangular hollow sections of high strength steel with measured 0.2% proof stress ranged from 679 to 1025MPa. The measured web slenderness values of the tubular sections ranged from 8.3 to 35.6. Tensile coupon tests were performed to obtain the material properties. The web crippling tests were conducted under the End-Two-Flange (ETF) and Interior-Two-Flange (ITF) loading conditions as specified in the North American Specification and Australian/New Zealand Standard for cold-formed steel structures. The test strengths obtained from this study were compared with the design strengths calculated from the North American Specification, Australian/New Zealand Standard and European Code for cold-formed steel structures. The web crippling test results obtained from this study are valuable for the development of design rules for cold-formed high strength steel.
