Three series of tests were conducted on small scale aluminum models of single cess, folded plate structures with symmetrical cross sections. In the first series of tests, the models were supported on plexiglass plates at the ends and were subjected to uniform, symmetrical loads. In the second series, the models were subjected to asymmetrical loads. A third series of tests was made on the models with the ends and center supported on plexiglass plates and subjected to symmetrically applied, uniform loads. In the first two series of tests, the models were loaded into the post-buckling range. The load which caused a plate element to exhibit local buckling was determined from deflection profiles taken along the longitudinal direction of the model.
