【Abstract】 Experimental work about the stability bearing capacity of the full scale model of diaphragm braced Z purlin is introduced in which the Z purlin is under simulated wind uplift loading. The bearing capacity was calculated by three code formulas and compared to the tested results. The test results showed that in ‘Technical specification for steel structure of light weight buildings with gabled frames’,‘Technical code of cold formed thin wall steel structures’and ‘AS/NZS4600’, the standardized degree of safety is relatively high. The value in BlueScope Lysaght design form is close to the test result, the reliability accords with the request of standardizing , and has good economic benefits. The analysis of experiment showed that the joint between strut and Z purlin has remarkable function to the development of stability bearing capacity of purlin. Some suggestions have been put forward for the design and construction of the practical project.更多还原
