Base connections and structures including the base connections, kits for forming and methods of repairing the same

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;
• and
• 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
• 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 wherein the base connection further includes at least one flange plate integrally formed with or configured to be attached to the base plate, the at least one flange plate is oriented perpendicularly relative to the tope surface of the base plate, the at least one flange plate configured to be attached to the at least one structural fuse, wherein detaching the yielded structural fuse from the base connection include 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.
