Fail-soft, graceful degradation, structural fuse apparatus and method
A retrofitting structure includes a column fixed in the ground. A structural fuse is pivotally mounted to the retrofitting structure at two vertically offset locations. The structural fuse is further pivotally mounted at a third location above the column to a superstructure of a building. The structural fuse is designed to yield for loads for which the column only deforms elastically. The structural fuse may be a planar member captured between the column and a retention plate to prevent buckling of the structural fuse. The retention plate may include a channel beam in order to provide sufficient stiffness to prevent buckling. Desired yield properties are obtained by increasing width of the structural fuse with distance from the bottom of the column. The width is augmented with distance from the bottom of the column to account for friction with the column and retention plate.
