  • Patent number: 5904025
    Abstract: A shear resisting member of a frame structure is formed from four triangular cross-section beams, each beam or stud formed from a single piece of cold formed sheet steel which is bent lengthwise along four parallel lines to form a triangular cross-section with two wings or flanges, side-by-side, extending from its apex. Within the frame structure of the shear resisting member, two frame beams have first beam lengths corresponding to the longer dimension of the opening in the wall to be reinforced, which are disposed parallel to each other. The other two beams have second beam lengths substantially shorter than the first beam lengths, the second beam length corresponding to the spacing between the frame studs or truss members of the structure being reinforced. Gussets are attached along the lengths of the wings or flanges of the second beams and the ends of the first beams to fasten the frame structure together.
