In this paper, an optimum design of GFRP bridge deck having a pultruded cellular cross-section is presented. The optimization process utilizes a modified genetic algorithm with the index technique. Based on the optimum design, viable cross-sectional dimension, volumes of fibers and matrix, fiber orientation, and stacking sequence for GFRP decks suitable for the pultrusion process are proposed.
