DEFLECTIONS AND CAMBER LOSS IN HEAT-CURVED GIRDERS
To check the camber loss in heat-curved girders, a 140-ft., simply supported span was instrumented during the construction of a bridge. The span was composed of four steel plate girders that have radii of curvature varying from 802.51 ft. on the inside to 834.51 ft. on the outside of the alignment curvature. Girder deflection and camber loss were measured before and after construction of the bridge deck. Some loss in camber from construction loading occurred shortly after placement of the concrete deck. The amount of loss, however, was only one-fourth of that determined from the AASHTO equation for predicting such loss. In addition, no significant camber losses were caused by service loading over a 6.5-month period subsequent to construction. (Author)
