COMPARATIVE STRUCTURAL BEHAVIOR OF STRAIGHT, CURVED AND SKEW REINFORCED CONCRETE BOX GIRDER BRIDGE MODELS

Comparisons of theoretical and experimental values of selected structural quantities, such as reactions, deflections and moments are presented for three large scale (1:2.8), two span, four cell, reinforced concrete box girder bridge models tested under dead load, working loads, and overloads, including loading to failure. All three models had the same cross-sectional and longitudinal span dimensions, but in plan one was straight, one was curved and one was skew. The models were 72 ft (21 m) long along the longitudinal centreline, 12 ft (3.7 m) wide and 1.71 ft (0.52) deep. Amounts of steel reinforcement used in the straight and curved model were similar, but in the skew model the amount was considerably less. General agreement was found between theoretical and experimental results. The structural response of the straight and curved models to point loads at midspan sections was similar, however that of the skew bridge was different and highly dependent on the transverse position of the applied point load. All three bridge models exhibited excellent behaviour with high overload capacities before ultimate failure. For the covering abstract see TRIS 393158. (Author/TRRL)
