BUCKLING AND FAILURE STRENGTH OF PLATING PANELS LOADED IN SHEAR. PART III: PRELIMINARY INVESTIGATION OF PANELS SUBDIVIDED BY TEE STIFFENERS
Abstract
The elastic critical shear buckling load was determined for clamped aluminum panels containing single central tee stiffeners. The panels were 0.050 in. thick, 30 in. long, and 6 in. wide between clamped edge and stiffener. Replaceable aluminum stiffeners, covering a range of torsional and flexural rigidity, were used. The stiffeners were bolted to the permanent base angles on the test panels. The observed critical stresses show a fair correlation with the critical stresses predicted from the solution developed by Crate and Lo. The test values were on the average 20% less than the computed values. The (comparatively light) stiffeners having proportions similar to those used in Naval construction provide something less than simple support to the panel; complete fixity was achieved only with very heavy tee sections.
