A member-to-member planar connection bracket that includes multiple repeated fuse element configurations that each provide a pre-determined inelastic load-carrying capacity and a reliable inelastic deformation capacity upon development of one or more inelastic hinge locations within the fuse elements. The fuse configurations are interconnected in series such that the total deformation accommodated between first end of the bracket and second end of the bracket is the sum of deformations accommodated by the individual fuse configurations. Multiple brackets are configured in laminar configurations and interconnected to create a connection assembly that provides increased strength or increased deformation capacity as compared to an individual bracket. The connection assembly is used to connect a first structural member and second structural member. The pre-determined maximum inelastic load-carrying capacity of the assembly is less than the elastic load-carrying capacity of the first structural member and the second structural member.

Member-to-member laminar fuse connection

A member-to-member connection bracket comprising a first connection member for coupling the connection bracket to a first structural member, a second connection member for coupling the connection bracket to a second structural member; and a fuse member disposed between the first connection member and the second connection member, the fuse member comprising at least one of hinge locations. The at least one hinge location provides inelastic deformation at a pre-determined load and the pre-determined load is less than the elastic yield load of a first structural member and a second structural member. The hinge locations may have a reduced thickness. The fuse member may have a tubular cross-section. A connection utilizing the member-to-member connection bracket is also included.

Member-to-member fuse connection

A mechanical damping system for a structure is provided. The mechanical damping system comprises a tubular impact frame secured to the structure. A support frame is secured to the structure with the support frame spaced from the impact frame. An elongated member is provided having a first end and a second end. The first end is secured within the support frame and the second end is free from connection and extends into the impact frame. At least one impact mass is secured to the second end of the elongated member, the impact mass movable within and contactable with the impact frame.
