  • Patent number: 6474902
    Abstract: A connector according to the present invention includes a bulk head for connection to a column and a plate extending from the bulk head for connection to a beam. The connector is preferably die cast for ease of manufacturing to avoid welded connections which may provide structural weaknesses. The bulk head has a compact tapered shape which provides a reduced surface area end surface coming into contact with the column. This reduced contact area of the end surface provides an advantageous configuration which avoids the prying action of the prior art T-shaped brackets. The plate which extends from the bulk head is adapted to be welded to a beam and includes a tapered portion that diminishes in a width dimension as the tapered portion extends away from the second surface to a free end. Preferably, the plate includes one or more tuning holes for adjusting the yield strength of the plate.

  • Patent number: 6073405
    Abstract: A fitting for effecting a bolted connection between a beam and a column in a steel frame structure includes a beam connecting portion and a column connecting portion. In addition, reinforcing elements are provided to strengthen the bracket and resist vertical eccentricity and loading caused by the particular bolted connection. The various embodiments of the bracket are particularly useful in the context of repairing cracked or damaged weld connections at the beam/column interface in existing steel structures, but have application in the context of upgrading or reinforcing existing weld connections that may not otherwise be damaged. Also, the bracket can be used in new steel frame constructions.
