Abstract
A modular structural section for use in support structures such as load bearing decks or highway bridges. The modular structural section includes at least one beam and a load bearing deck preferably formed of a polymer matrix composite material. The deck includes a core having elongated core members having side walls positioned generally adjacent one another. Preferably, at least one of the elongated core members has an upper and a lower facesheet extending beyond the side wall to receive another member. Also, preferably, the elongated core members have a polygonal, and more preferably a trapezoidal, shape. Alternatively, the load bearing deck contains at least one sandwich panel suitable for applications such as barge decks, hatchcovers, and other load bearing wall applications. Methods of constructing a support structure utilizing the novel modular structural section and support members are also provided.
