This paper describes the field testing of the Aguasabon River bridge in Ontario, a three-span, continuous, steel girder bridge with parabolic haunches of composite concrete slab construction. As part of the 1973 bridge testing program, the structure was tested both statically and dynamically with two load-testing vehicles. Because this structure had a history of failures of the haunch weld detail and because it was one of several similarly designed structures, it was decided to determine the actual bridge behavior under load as well as its structural adequacy. Outlined are the grid type and other analytical procedures followed to predict stresses and deflections, which are then compared with those values recorded during the static loading. An estimate of the fatigue life of the weld details is made by using the dynamic strain data obtained. General aspects of the behavior of the structure are discussed, and conclusions are drawn on the structural adequacy of the test bridge and the methods used in the analysis and testing.
