    摘要: A shear resisting member of a frame structure comprising 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. A plurality of strut members span the interior edges of the first beams to form an open web between the two first beams. The strut members, each formed from sheet steel folded or creased to form triangular cross-sections, are fastened to the first beams at angles to provide shear resistance in a plurality of different directions. A method for retrofitting existing structures to provide reinforcement against shear forces comprises identification of weight-bearing walls and removal of interior wall paneling, such as dry wall, to expose the frame along sections of the wall. A shear panel is selected to have horizontal dimensions to fit between two adjacent wall studs, and vertical dimensions to extend from the foundation or floor joist to the roof truss or floor joist of an upper story for multi-level structures. The original wall studs are removed and the panel is inserted along with replacement wall studs.
