  • Patent number: 8701359
    Abstract: A cast structural connector connects a structural member, such as a hollow structural section (HSS) or wide flange (W) section member, to a structural frame. The connector is particularly suited for lateral bracing and includes a first end configured to receive the structural member and be welded to the structural member, a second end for connecting to the structural frame, and an intermediate portion. The first end includes beveling allowing compatibility with structural members of varying sizes and enabling complete joint penetration welding thereby developing the full axial strength of the structural member. The intermediate portion provides for transmission of forces as the frame deforms, for example, under severe seismic conditions, and can include a flexural plastic hinge portion. The connector can be welded to the structural frame or connected by a standard fabricated end connection, such as a gusset plate. Casting manufacturing allows for mass production of the connector.

  • Patent number: 8683758
    Abstract: A yielding fuse device is provided for use in association with a brace member in a bracing assembly for a structural frame. The device includes arms or elements that yield flexurally when a bracing member moves in an axial direction, with the bracing assembly under either tension or compression loading conditions. The device of the present invention is particularly useful as a mass customized cast device. The device is well suited for seismic bracing applications.
