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.

First claim

What is claimed is:

1. A pair of structural fuse assemblies, comprising:
a first blank taken from a first section of a beam, the first blank comprising:
a first structural fuse comprising;
a first fuse base formed from a first flange of the beam,
a first 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 first pair of spacers formed from the web of the beam and configured to fit within the pair of notches; and
a first buckling restraint plate formed from a second flange of the beam; and

a second blank taken from a second section of the beam, the second blank comprising:
a second structural fuse comprising;
a second fuse base formed from the first flange of the beam,
a second 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 second pair of spacers formed from the web of the beam and configured to fit within the pair of notches; and
a second buckling restraint plate formed from a second flange of the beam;
wherein the first and second sections of the beam are directly adjacent each other on the beam.

2. The structural fuse assembly of claim 1 , wherein the beam is a structural steel component with a standard structural W-shape.

3. The structural fuse assembly of claim 1 , wherein a grain of the pair of spacers aligns with a grain of the fuse yield plate upon positioning the pair of spacers in the pair of notches.

4. 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; and
wherein a grain of the pair of spacers aligns with a grain of the fuse yield plate upon positioning the pair of spacers in the pair of notches.

5. The structural fuse assembly of claim 4 , wherein the structural steel component is a standard structural W-shape beam.

6. The structural fuse assembly of claim 4 , wherein the structural steel component is standard structural W-shape beam and wherein the fuse base is formed from a flange of the beam and the fuse yield plate is formed from a web of the beam.

7. The structural fuse assembly of claim 6 , wherein the flange comprises a first flange, and wherein the buckling restraint plate is formed from a second flange of the beam.

8. The structural fuse assembly of claim 6 , wherein the pair of spacers are formed from the web of the beam.

9. The structural fuse assembly of claim 8 , wherein the pair of spacers are formed from a portion of the web cut out to form the notches.

10. The structural fuse assembly of claim 8 , wherein the flange is a first flange, and wherein the pair of spacers are formed from a portion of the web between and end of the structural fuse yield plate and a second flange of the beam.

11. 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,
a fuse yield plate extending from and integrally formed with the fuse base, the fuse yield plate comprising a narrow section defined by a pair of notches in opposed edges of the fuse yield plate, the fuse yield plate formed from a web of the beam, and
a pair of spacers configured to fit within the pair of notches;

wherein a grain of the pair of spacers aligns with a grain of the fuse yield plate upon positioning the pair of spacers in the pair of notches.

12. The structural fuse assembly of claim 11 , the blank further comprising a buckling restraint plate formed from a second flange of the beam.

13. The structural fuse assembly of claim 11 , further comprising a buckling restraint plate.

14. The structural fuse assembly of claim 11 , wherein the buckling restraint plate comes from the beam.

15. The structural fuse assembly of claim 11 , wherein the fuse yield plate comprises a narrow area defined by a pair of notches, the structural fuse assembly further comprising a pair of spacers configured to fit within the pair of notches.

16. The structural fuse assembly of claim 15 , wherein the pair of spacers are formed from the web of the beam.
