The base tGSt method has been proposed by Carballo, Holzer and Murray
 as a means of determining the strength of standing seam roof systems under
gravity loading. The objective of this thesis is to evaluate the accuracy of the base
test method. To do this, eleven sets of tests were performed at Virginia
Polytechnic Institute & State University (VPl&SU). Each test set consisted of a
single span base test from which a failure load was predicted for the
corresponding three span confirming test. Results of two test sets recorded in
Reference  were also used to evaluate the method. A secondary objective of
this thesis is to comment on the effects that system components (purlin
orientation, clip type, bracing configuration, panel type, insulation and purlin type)
have on the strength of the system. Results from proprietary tests conducted at
VPI & SU were used in conjunction with the results from this research to
accomplish the secondary objective.
