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.

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

Embodiments are directed to structural fuses, structures including the same, and methods of using and forming the same. In an embodiment, a structural fuse is disclosed. The structural fuse includes a first attachment region defining one or more first bolt holes, a second attachment region defining one or more second bolt holes, and a yielding region between the first attachment region and the second attachment region. The yielding region defines one or more slots exhibiting an elongated shape.

Structural fuses configured to yield in tension and compression and structures including the same

Embodiments are directed to structural fuses and connection systems including the same. An example structural fuse includes at least one plate. The structural fuse includes a plurality of cutouts formed in the plate. The cutouts are configured to cause at least one first yield region of the plate to yield when a first load is applied to the plate. Optionally, the plurality of cutouts are configured to cause at least one second yield region to yield when a second load is applied to the plate. At least a portion of the first yield region is distinct from at least a portion of the second yield region and the first load is different than the second load.

Structural fuses and connection systems including the same

Embodiments disclosed herein relate to a beam-to-column connection systems for a moment-resisting frame as well as moment-resisting frames that include such connection systems.
