SHEAR-LAG TESTS OF WO BOX BEAMS WITH CORRUGATED COVERS LOADED TO FAILURE

摘要

Strain measurements were made on the compression side of two box beams with corrugated aluminum-alloy covers loaded to failure. Angles formed from sheet were used for corner flanges in beam 1;whereas extruded angles were used in beam 2. By use of the shear-lag theory the stresses in the corner flanges at the root could be predicted to approximately 10 percent for beam 1 and 5 percent for beam 2. Failure in each beam occurred in the corner angle at a stress that was above the compressive yield stress for the material.
