Roof systems constructed using cold-formed steel components, i.e., Z-shaped purlins and interconnected roof panels, have become a very popular form of construction. This roof system is used extensively for single-story commercial and industrial buildings in the United States.

Web crippling behaviour of nested Z-purlins
Engineering Structures, 1994Abstract The findings of three research projects that focused on the web crippling behaviour of nested Z-sections are summarized. The nested Z-section is utilized by the metal building industry in the USA for continuous span roof purlin systems. Present design provisions in the USA, do not specifically address this configuration. Experimental studies

Cold-formed purlin-sheeting systems
2002Purlin-sheeting systems used for cladding in roofs and walls commonly consist of cold-formed channel or zed section purlins, screw-connected to corrugated sheeting. This paper presents a nonlinear finite element model for purlin-sheeting systems.

Numerical study of purlin joints with sleeve connections
Thin-Walled Structures, 2015Abstract The joint behaviour influences the stresses and deformations developed by the structure. Based on a predesign for the structural efficiency, a numerical study of cold formed purlins joints with sleeve connections has been performed, allowing for the actual joints structural behavior. The moment rotation curves of the joint configurations are

Poplar wood for purlins; an evaluation of options and environmental aspects
Holz als Roh- und Werkstoff, 1998The poplar is now applied mostly for low quality products with a short life span. Six options for a higher quality application, in this case a polar purlin, are presented and semi quantatively evaluated with regard to their environmental aspects.

Governing Stresses in Z-Purlin Lap Joints
Journal of Structural Engineering, 1995Twenty-eight stiffened Z-section beams were transversely loaded to failure and stresses in the lap joints were investigated. Spans of 2.438 m (8 ft) were used. The tested sections were of web depth-to-thickness ratios (\ih/\it) ranging from 79 to 131, and were selected from those commonly used by the metal building industry. The tests included a single-

Design of thin-walled purlins for distortional buckling
Thin-Walled Structures, 1997Abstract Roof purlins and sheeting rails are generally loaded through the cladding members that they support and this provides both rotational and translational restraint. This restraint reduces the tendency to lateral torsional buckling and thus increases the importance of distortional buckling in the design procedure.
