Abstract: A structural fuse is disclosed including a fuse base and a fuse plate extending from the fuse base. The fuse plate may include a reduced diameter yield section configured to yield at loads on the structural fuse above a threshold. The reduced diameter yield section includes a pair of slots on either side of the yield section, which slots receive a pair of spacers. The spacers are integrally formed as part of the fuse plate, and remain attached to the fuse plate during fabrication of the structural fuse.

Abstract: A one-piece structural fuse assembly is disclosed that is formed from a single piece of structural steel such as a beam. In embodiments, a first flange of the beam may form the fuse base, and a portion of the web of the beam may form the fuse plate. Additionally, a buckling restraint plate of the structural fuse assembly may be formed from a second flange of the beam, and the spacers of the structural fuse assembly may be formed from a portion of the web unused by the fuse plate. In examples, all of the components cut from the single piece of the beam are used in a single structural fuse assembly.
