The Kentucky Transportation Center (KTC) was requested by the Stor-Mor Corporation (SMC) to test a number of building panels that SMC uses to build small storage buildings and small recreational structures. SMC delivered to the KTC laboratories a number of the panels to be tested in bending and other modes as deemed appropriate by KTC. The panels are of sandwich construction consisting of two, thin sheet metal plates and a styrofoam interlayer. Each panel was approximately 64 inches in length and 22 inches in width. The thickness was approximately 1.63 inches.

This report details the testing of the panels and includes the test data along with comments and recommendations. The panels were tested in what was perceived to be the two weakest modes of failure. These were in bending and in "pull-out" of the screw heads that are used to assemble the panels.
