  • Modular polymer matrix composite support structure and methods of constructing same
    Patent number: 6081955
    Abstract: A load bearing support structure in the form of a traffic-bearing highway bridge including at least one modular structural section. The at least one modular structural section includes at least one beam, the at least one beam containing a pair of lateral flanges and a medial web between and extending below the flanges. A load bearing deck is positioned above and supported by the flanges of the at least one beam. The at least one beam and load bearing deck are preferably formed of a polymer matrix composite material. Each of the flanges of the at least one beam is positioned on and supported by one of a plurality of support members. Alternatively, the load bearing deck containing at least one sandwich panel is suitable for applications such as barge decks, hatchcovers, and other load bearing wall applications. Methods of constructing a support structure utilizing the modular structural section and support members are also provided.
