Abstract:

Results obtained in a study of a large-scale, two-span, four cell reinforced concrete bridge model are presented. The model, which was a 1:2.82 scale replica of a prototype, had overall plan dimensions of 72 ft (21 m) long by 12 ft (3.7 m) wide. The various computer programs used in obtaining theoretical results are described and compared. Experimental and theoretical results are given for reactions, deflections, and moments due to working stress point loads applied before and after overload stress levels in the bridge. Conclusions are presented on the adequacy of the theory in predicting bridge response.
