One-piece structural fuse

A structural fuse assembly, comprising:

• a structural fuse comprising;
• a fuse base,
• a fuse yield plate extending from and integrally formed with the fuse base, the fuse yield plate comprising a narrow area defined by a pair of notches;
• a pair of spacers for fitting within the pair of notches;
• and
• a buckling restraint plate;
• wherein the structural fuse, the pair of spacers and the buckling restraint plate all come from a single section of a structural steel component.

A structural fuse assembly, comprising:

• a blank taken from a section of beam, the blank comprising:
• a structural fuse comprising;
• a fuse base formed from a first flange of the beam,
• a fuse yield plate extending from and integrally formed with the fuse base, the fuse plate formed from a web of the beam, and the fuse yield plate comprising
• a narrow area defined by a pair of notches;
• a pair of spacers formed from the web of the beam and configured to fit within the pair of notches;
• and
• a buckling restraint plate formed from a second flange of the beam.

A structural fuse assembly, comprising:

• a blank taken from a section of a beam, the blank comprising:
• a structural fuse comprising;
• a fuse base formed from a first flange of the beam, and
• a fuse yield plate extending from and integrally formed with the fuse base, the fuse plate formed from a web of the beam.

A method of fabricating a structural fuse assembly, the method comprising:

• (a) cutting a blank from a structural steel component including at least a first flange and a web extending orthogonally from the first flange and integrally formed with the first flange;
• (b) forming the first flange of the blank into a fuse base of the structural fuse assembly;
• and
• (c) forming the web of the blank into a fuse yield plate of the structural fuse assembly by forming bolt holes in the web and cutting a pair of notches in the web to define an area having a width that is narrower than adjacent areas of the web.
