Abstract

The paper describes a test program on purlin-sheeting systems for which the sheeting was screw fastened to the purlins. The test program simulates downwards loading. Z-section purlins were tested in three span continuous lapped configurations. The test purlins were supported by a range of bridging (bracing) members ranging from no bracing to one brace per span. The test results are compared with the design values computed using the Australian Cold-Formed Steel Structures Standard (AS1538-1988). The Australian Standard design is based on a flexural-torsional buckling analysis which may include the restraint from attached sheeting.

Tests of Continuous Purlins under Downwards Loading

Saint Louis, Missouri

The paper describes a test program on purlin-sheeting systems for which the sheeting was screw fastened to the purlins. The test program simulates downwards loading. Z-section purlins were tested in three span continuous lapped configurations. The test purlins were supported by a range of bridging (bracing) members ranging from no bracing to one brace per span. The test results are compared with the design values computed using the Australian Cold-Formed Steel Structures Standard (AS1538-1988).
