THERMAL STRESSES INDUCED IN A COMPOSITE MODEL BRIDGE STRUCTURE

This experimental investigation was conducted to verify a prior theoretical study. The objectives of the study were a) to construct and instrument a 15 ft.-15 ft. (4.6 m-4.6 m) two-span, continuous, composite, laboratory structure; b) to subject the structure to thermal loading; and c) to correlate the experimental temperature distributions, strain distributions, and deflections with those obtained from the theoretical study. It was concluded that the theoretical procedure provides a rational method for predicting the thermal behavior of composite-girder bridge structures and can be applied with reasonable confidence when used with relistic temperature profiles, material properties, and substructure stiffness characteristics. /Author/
