Abstract: A structural member section comprised of horizontal top and bottom flange elements interconnected by one or more vertical web member. The top flange of the member is serrated such that a series of serrations protrude horizontally in at least one direction from a top of the one or more vertical web member or are cut-out from the flange of a rolled shape. In one embodiment, the serrated top flange and at least a portion of the web member are intended to be encased by a horizontal concrete slab or slab-on-deck assembly. The slab material is capable of encasing all exposed surfaces of and curing around each serration to transfer horizontal shear forces between the serrated top flange and the slab material such that the member and slab behave compositely.

Abstract: 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.

Abstract: 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.
