Abstract

Embodiments are directed to base connections, structures including base connections, kits for forming the base connections and/or structures, and method of repairing yielded base connections. In an embodiment, a base connection includes a base plate including a top surface and a bottom surface opposite the top surface. The top surface is configured to be adjacent to a terminal end of a column and the bottom surface adjacent to a foundation. The connection also includes one or more anchor rods attached to the base plate. The anchor rods are configured to secure the base plate to the foundation. The connection includes at least one structural fuse configured to be attached to the column and attached to the base plate. The fuse includes a plate with at least one cutout formed therein. The cutout is configured to form one or more yield regions that are configured to preferentially yield. The base connection also includes at least one flange plate directly attached or integrally formed with the base plate and the at least one flange plate is also attached to the at least one structural fuse.

Claims (18)

1. A base connection, comprising: a base plate including a top surface and a bottom surface opposite the top surface, the top surface configured to be adjacent to a terminal end of a column and the bottom surface adjacent to a foundation; one or more anchor rods attached to the base plate, the one or more anchor rods configured to secure the base plate to the foundation; at least one structural fuse configured to be attached to the column and attached to the base plate, the at least one structural fuse including a plate with at least one cutout formed therein, the at least one cutout configured to form one or more yield regions extending therefrom that are configured to preferentially yield relative to other regions of the plate; and at least one flange plate directly attached or integrally formed with the base plate, the at least one flange plate attached to the at least one structural fuse.
2. The base connection of claim 1, wherein the at least one structural fuse includes two structural fuses, each of the two structural fuses secured to one of two flanges of the column.
3. The base connection of claim 1, wherein the plate of the at least one structural fuse exhibits a thickness of about 0.5 cm to about 8 cm.
4. The base connection of claim 1, wherein each of the one or more yield regions extend from the at least one cutout in a first direction.
5. The base connection of claim 1, wherein the at least one cutout includes a plurality of cutouts separated by a spacing of about 5 cm to about 15 cm.
6. The base connection of claim 1, wherein the at least one cutout exhibits a maximum length and a width measured perpendicular to the maximum length that is less than the maximum length, the width is about 2.5 cm to about 25 cm.
7. The base connection of claim 1, wherein the at least one structural fuse is bolted to the column.
8. The base connection of claim 1, wherein the at least one structural fuse is welded to the column.
9. The base connection of claim 1, wherein the at least one structural fuse directly contacts the column. - Page 18 - 48730057\1
10. The base connection of claim 1, wherein the at least one flange plate includes at least one opening that provides access to at least one region of the at least one structural fuse.
11. The base connection of claim 10, wherein: the at least one structural fuse is configured to be bolted to the column; and the at least one opening provides access to portions of the at least one structural fuse that are bolted to the column.
12. The base connection of claim 1, wherein the base connection is a fully–restrained connection.
13. A structure, including: a column; a foundation; and a base connection including: a base plate including a top surface and a bottom surface opposite the top surface, the top surface configured to be adjacent to a terminal end of a column and the bottom surface adjacent to a foundation; one or more anchor rods attached to the base plate, the one or more anchor rods secure the base plate to the foundation; at least one structural fuse attached to the column and the base plate, the at least one structural fuse including a plate with at least one cutout formed therein, the at least one cutout configured to form one or more yield regions extending therefrom that are configured to preferentially yield relative to other regions of the plate; and at least one flange plate directly attached or integrally formed with the base plate, the at least one flange plate attached to the at least one structural fuse.
14. A kit, comprising: a base plate including a top surface and a bottom surface opposite the top surface, the top surface configured to be adjacent to a terminal end of a column and the bottom surface configured to be adjacent to a foundation; at least one structural fuse configured to be attached to the column and the base plate, the at least one structural fuse including a plate with at least one cutout formed therein, the at least one cutout configured to form one or more yield regions extend therefrom that are configured to preferentially yield relative to other regions of the plate; and - Page 19 - 48730057\1 at least one flange plate directly attached or integrally formed with the base plate, the at least one flange plate attached to the at least one structural fuse.
15. The kit of claim 14, further comprising the column.
16. A method of repairing a yielded structural fuse, the method comprising: detaching the yielded structural fuse from a column and a base plate, the base connection including: the base plate including a top surface and a bottom surface opposite the top surface, the top surface adjacent to a terminal end of the column and the bottom surface adjacent to a foundation; one or more anchor rods attached to the base plate, the one or more anchor rods securing the base plate to the foundation; at least one structural fuse including a plate with at least one cutout formed therein, the at least one cutout configured to form one or more yield regions extend therefrom that are configured to preferentially yield relative to other regions of the plate, the at least one structural fuse including the yielded structural fuse; and at least one flange plate directly attached or integrally formed with the base plate, the at least one flange plate attached to the at least one structural fuse; and attaching a new structural fuse to the column and the base plate, the new structural fuse including a new plate with at least one new cutout formed therein, the at least one new cutout configured to form one or more new yield regions extending therefrom that are configured to preferentially yield relative to other regions of the plate.
17. The method of claim 16, wherein: detaching the yielded structural fuse from the base connection includes unbolting the yielded structural fuse from the column; and attaching the new structural fuse to the column and the base plate including bolting the new structural fuse to the column.
18. The method of claim 16, wherein detaching the yielded structural fuse from the base connection includes detaching the yielded structural fuse from the at least one flange plate and attaching the new structural fuse to the column and the base plate includes attaching the new structural fuse to the at least one flange plate. - Page 20 - 48730057\1 1 / 6 150 120 120 116 104 112 102 140 150 134 110 126 2 / 6 146 148 3 / 6 138 136 138 140 140 4 / 6 104 150 126 110 5 / 6 138 138 140 140 Detaching the yielded structural fuse from the column and a base plate Attaching a new structural fuse to the column and the base plate 6 / 6 550 550 550 550 502 502 502 502 502
