This research reports a numerical study on the flexural strength of single-lipped Zed-Purlin sections under two equal moments applied at the ends of the specimen. The effects of attaching corrugated steel sheeting to the tension flange of Z-purlins on the structural behavior are investigated. The studied parameters of the specimens are: types of corrugated steel sheeting, depth-to-thickness ratio, and the span of the purlins. Linear and non-linear analyses using finite element software are conducted. Results show that a tension flange braced by corrugated steel sheeting can increase the section capacity of Z-purlins and change the failure mode. The results of the ultimate moment obtained from finite element analysis have been compared to both the nominal flexural strength according to the Egyptian code (ECP) and the North American Specifications (AISI). The results of purlins with sheeting determined by ECP are conservative due to ignoring the effect of corrugated steel sheeting on capacity, while the results from AISI are in good agreement with finite element analysis as they take into account the effect of sheeting.

“…Conducted test on 71 built-up members to study the buckling behaviors of the compressive built-up cold-formed members. A numerical parameter study on the loading capacity of channel purlins with screw-fastened sheeting was also presented by Zhang et al (2018). Bai et al (2018) proposed a modified Direct Strength Method (MDSM) to calculate the simply supported C-section purlin under wind uplift.…”

This article presents a study on the impact of the screw location and the diaphragm effects on the buckling behavior of the simply supported C/Z-section purlins under wind uplift loadings. The diaphragm effects provided by the sheeting and the warping-torsional effect induced by load eccentricity are taken into account in the differential equations of the nonlinear twisting flexural-torsional model. The biaxial bending moments, bi-moments, as well as the flexural-torsional buckling load of the purlin can be numerically obtained with the proposed model. The global, local, and distortional buckling interaction behavior and the limit states capacities are formulated based on the modified Direct Strength Method. The effects of both the restraints provided by the sheeting and impact of the screw location on the mechanical performance of the purlins are evaluated with the proposed method. The relationship between the buckling load and rotational restraint stiffness is also provided. The proposed methodology will contribute to the assessment of buckling capacity of purlin-sheeting systems.
