  • Patent number: 8752225
    Abstract: A method and apparatus for adjusting the live and dead load balance between the arches of an arch bridge and the truss girder that supports the bridge deck. The method is achieved by providing hanger rods disposed between the arches and the top chords of the truss girder whose compression may be adjusted. In which the arch truss counter act the compression in the top chord of the truss. This interaction adds to the strength and safety of both elements of the structure. With this interaction there are no critical members which can cause catastrophic failure of the bridge by failing. By combining two of these bridges side by side, and then connected with the lateral members, both at top and bottom chord of trusses, it is possible to carry vehicular, train, and pedestrian lanes separated and accommodated with safety; all without a critical member.

  • Patent number: 7845117
    Abstract: This invention concerns an arch structure. In particular, the invention relates to an arch structure comprised of at least two segments which are rotatably linked to each other via hinges or equivalent means to form a continuous bendable chain of attached segments. The segments have magnets above the rotatable or hinged link on opposed end faces, positioned to oppose magnets on confronting end faces of adjacent arch segments, with like poles facing one another, thereby creating a repulsion force. The repulsion force inhibits the arch segments from being brought together and into contact. Due to this effect, the aggregate of the arch segments define an arcuate path (convex upward), maintained by the repulsion forces of the magnets.

  • Patent number: 5784738
    Abstract: A hinge connects the webbing of a first bridge span to the webbing of a second bridge span. The hinge has male hinge plates on opposite sides of the first span's webbing and has female hinge plates on opposite sides of the second span's webbing. A shaft passing through the male hinge plates and first span's webbing is threaded on the ends but is smooth between the ends. Pockets at outer surfaces of the male plates surround the threaded ends and accept torque limiting nuts engaging the shaft. The nuts have heads, recess bodies and frangible necks connecting the heads to the bodies. No part of the bodies extends past the outer surfaces of the male plates. When the nuts are driven onto the shafts at a given torque, the necks break and the heads twist off. Then any remaining parts of the necks are removed. The male hinge plate can then be rotatably mounted adjacently between the female hinge plates.
