Month in the Patent Office

Abstract

The web portion 1 of a structural member which is formed of a light metal or alloy is apertured or reduced in thickness at certain portions for the purpose of weight reduction, and tics 4 formed of a material having a relatively greater tensile strength than the material of the structural member are disposed obliquely across the weakened portions of the web so as to offer a tensile resistance to those forces producing shear stresses in the web. The ties may be in the form of flat steel links 4 which are secured by rivets 5 on both sides of the web as shown in Figs. 1 and 2. Alternatively the ties may be in the form of continuous strips of zigzag formation. The structural member may be of I‐, T‐, or U‐cross‐section.
