Uplift Capacity of Z‐Purlins

Journal of Structural Engineering, 1991
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.

Sleeve connections of cold-formed steel sigma purlins

Engineering Structures, 2012
Abstract Cold-formed steel sigma purlins normally possess advantageous structural features such as an enhanced web buckling resistance and a location of shear centre closer to the web. In modern roof construction, typical connections for sigma purlins include butt, continuous and sleeve systems.

Numerical study of purlin joints with sleeve connections

Thin-Walled Structures, 2015
Abstract 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

Optimization of Long-Span Cold-Formed Truss Purlins

Journal of the Structural Division, 1974
The value of mathematical optimization tools for the cold-formed steel industry is investigated by using a particular technique to redesign a building systems product already being successfully marketed. The optimization technique employed is a variation of the cutting-plane method wherein a sequence of linear programming problems is solved to obtain ...

The strength and performance of cold formed steel purlins

Construction and Building Materials, 1988
Abstract An experimental and computer based investigation was carried out on a range of locally manufactured cold formed steel purlin sections to assess their behaviour at both serviceability and ultimate load levels. The test programme and test facility are described and a selection of typical results presented and discussed.

2A Industry Applications: Computer Makes Precise Purlins

1985
Erectors of steel-frame buildings may not realize that the purlins they get from Molenco (Houston) are now sized with help from a microprocessor and a brushless AC servo drive. But these commonly used structural members are roll formed in C and Z cross sections from blanks precisely cut to specified length, and punched with rivet or bolt holes, if ...
