The paper gives a comparative analysis of three different existing sets of shear diaphragm buckling formulas, and develops therefrom a single highly simplified formula for the buckling loads for light-gage corrugated metal shear diaphragms. Buckling experiments on precision small-scale diaphragm specimens are also described, which show, along with the comparative analysis of the different buckling formulas, that the simplified formula accurately predicts shear diaphragm buckling.
