Standing seam roof system strength under uplift loading

Abstract

The objective of this thesis is to verify the "base 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 base test method for uplift loading, in its present form, did not prove to be an effective method for determining the failure load of a multispan, multi-purlin line, standing seam roof system. Suggestions are made for possible modifications to the method.
