Abstract: A ductile anchor attachment (DAA) mechanism is disclosed. Example embodiments are directed to a DAA fuse plate including a bottom section configured to connect to an existing anchor; a tapered lower section; a narrowed neck forming a ductile yield mechanism; a tapered upper section; and a connection mechanism for direct removable coupling of the DAA fuse plate to a structure being anchored, the connection mechanism being in contact with the tapered upper section of the DAA fuse plate, the DAA fuse plate in combination with the connection mechanism being configured to not buckle under compression forces and to adjustably dissipate tension forces acting on the structure being anchored.

Abstract: A ductile anchor attachment (DAA) mechanism is disclosed. Example embodiments are directed to a DAA mechanism having a bottom section configured to connect to an existing anchor; a tapered lower section; a narrowed neck forming a ductile yield mechanism; a tapered upper section; a drilled and untapped top section; and a hollowed interior. Example embodiments are also directed to a DAA mechanism comprising: a headed rebar with a rebar coupler; a rebar segment coupled to the rebar coupler at a first end of the rebar segment; a metal jacket encasing at least a portion of the rebar segment; and a flange connection bracket coupled to the rebar segment at a second end of the rebar segment.
