An example structural fuse includes a first attachment region configured to be attached to a first structural element, a second attachment region configured to be attached to a second structural element, and at least one yielding region extending between the first and second attachment regions. The yielding region exhibits a geometry that is selected to allow the structural fuse to maintain a strength thereof even as the structure fuse yields (e.g, buckles). For example, the yielding region exhibits a length, a minimum width, and a thickness and one or more of the length, minimum width, or thickness of the yielding region is selected to allow the structural fuse to maintain its original strength even as the structure fuse yields and buckles.

Various embodiments disclosed herein relate to moment-resisting frames, kits for assembling such moment-resisting frames, and methods of repairing such moment-resisting frames. In an embodiment, a moment-resisting frame includes a beam connected to a column using a moment-resisting connection. The moment-resisting connection may include at least one exterior doubler plate (“EDP”) that is connected to the column and two or more connectors that are connected to both the beam and the EDP. In some embodiments, the moment-resisting frame may require less welding than conventional beam-to-column connections. Additionally or alternatively, such a moment-resisting frame may eliminate the need for components typically used in conventional beam-to-column connections (e.g., continuity plates).
