Abstract

NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document.

A program of experimental investigation for three combinations of sheet reinforced with corrugations has been carried out.

An assumption has been made for the transverse neutral axis of such a system.

For an open section box beam, the conventional assumption of the neutral axis on the center of gravity plane indicates an error.

An attempt has been made to calculate the compressive stress in each corrugation due to shear transfer of load.

An effective shear modulus for each corrugation and its share of the skin under bending loads has been found by experimental methods.

For the combinations tested, it was found that the effective shear modulus, G/E, decreases with increasing [...], which corresponds to increasing G/E with distance from the free end of the panel.

Panel curvature was found to have a marked effect on G/E, in that the curved panel had a larger value of G/E for the same [...].

Contour maps of [...], the shearing stress, have been constructed for the three panels.
