Abstract

The purpose of this research was to determine the axial load capacity of Z-purlins with one flange attached to a standing seam roof system. The axial load capacity was determined by developing a relationship between the flexural uplift buckling strength and the axial buckling strength in the Z-purlin. This relationship was investigated using finite element models and by conducting a parametric study. At the conclusion of the parametric study, confirmatory tests were conducted to verify the finite element results. A relationship has been provided that relates the axial buckling strength in the Z-purlin to the flexural uplift buckling strength. This paper is a condensed version of the MBMA Research Report 99-02 (MBMA 2001).

Axial Strength of Purlins Attached to Standing Seam Roof Panels

The purpose of this research was to determine the axial load capacity of Z-purlins with one flange attached to a standing seam roof system. The axial load capacity was determined by developing a relationship between the flexural uplift buckling strength and the axial buckling strength in the Z-purlin. This relationship was investigated using finite element models and by conducting a parametric study. At the conclusion of the parametric study, confirmatory tests were conducted to verify the finite element results. A relationship has been provided that relates the axial buckling strength in the Z-purlin to the flexural uplift buckling strength.
