Abstract

A test program on purlin-sheeting systems with concealed fasteners has been performed at the University of Sydney in a vacuum test rig. The test rig used a conventional vacuum box to simulate wind uplift. Z-section purlins were tested in three span lapped configurations, and as simple spans. The test purlins were supported by a range of bracing (bridging) members ranging from zero to two braces per span. In addition, a range of section slenderness values was used so as to precipitate both local buckling and yielding failures in the section. The purpose of the paper is to compare the test results with design loads in the Australian Standard AS 1538-1988 based on a flexural-torsional buckling analysis.

Tests of Purlins with Concealed Fixed Sheeting

Saint Louis, Missouri

A test program on purlin-sheeting systems with concealed fasteners has been performed at the University of Sydney in a vacuum test rig. The test rig used a conventional vacuum box to simulate wind uplift. Z-section purlins were tested in three span lapped configurations, and as simple spans. The test purlins were supported by a range of bracing (bridging) members ranging from zero to two braces per span. In addition, a range of section slenderness values was used so as to precipitate both local buckling and yielding failures in the section. The purpose of the paper is to compare the test results with design loads in the Australian Standard AS 1538-1988 based on a flexural-torsional buckling analysis.
