Strength of z-purlin supported standing seam roof systems under gravity loading
… develop a design procedure for the strength of Z-purlin supported standing seam roof systems under gravity leading. Various approaches were taken to calculate the strength of systems with either torsional restraint, third point span restraint, or midspan restraint. Since few test results are …

Estimation of Required Restraint Forces in Z-Purlin Supported, Sloped Roofs Under Gravity Loads
… the prediction of lateral restraint forces in Z-purlin supported roof systems under gravity loads are in Section D3.1 of the 1996 AISI Cold-Formed Specification. The design equations contained in these provisions are empirical and based on statistical analysis. They were developed using elastic …

Experimental Determination of Required Lateral Restraint Forces for Z-Purlin Supported, Sloped Metal Roof Systems
… required lateral restraint forces in Z-purlin supported, sloped metal roof systems under gravity loads. A proposed prediction equation, relying heavily on engineering principles, has been developed because the current provisions in the specification are empirical and based on statistical …

Lateral Restraint Brace Forces in Quarter Point and Third Point Plus Support Braced Z-Purlin Supported Roof Systems Subject to Gravity Load
… lateral restraint forces in two commonly used Z-purlin supported roof systems. These are quarter point bracing and third point plus support bracing. To that end, a stiffness model used in the past has been reintroduced. This model has been modified slightly to better represent roof system …

Standing seam roof system strength under uplift loading
… test method" for uplift loading of C- and Z-purlin supported, standing seam metal building roof systems. To achieve this end, eight sets of full-scale roof system tests were conducted. Each test set consisted of a single span base test and a three-span, multi-purlin line, confirming test. The …

Investigation of Inflection Points as Brace Points in Multi-Span Purlin Roof Systems
… inflection points as brace points in multi-span purlin roof systems. Seven tests were conducted using "C" and "Z" purlins attached to standing seam and through fastened panels. These tests were subjected to uniform gravity loading by means of a vacuum chamber. The experimental results were …

Further Study of the Gravity Loading Base Test Method
… moment strength of a multiple span, multiple purlin line standing seam roof system using the results from a set of six single span, simply supported, two-purlin line experimental tests. A set of six base tests must be conducted for each combination of purlin profile, deck panel profile, clip …
