Abstract:
This paper focuses on the development of a theoretical model for predicting the behavior of laterally-restrained, fiber-reinforced concrete bridge decks. Based on observations of the failure modes in experimental testing and a review of models used for the punching failure of reinforced concrete slabs, a rational model is developed. The assumptions and equations used in the model development are presented along with the solution algorithm. The theoretical model is checked through comparison with several half-scale and full-scale tests on laboratory bridge decks. The results of the experimental programs are recorded elsewhere and listed in the references.
