Abstract

"This experimental investigation was conducted as an intermediate study to verify and substantiate a prior theoretical study for possible utilization toward development of rational bridge design criteria. The objectives of the study were to construct and instrument a 15 ft - 15 ft (4.6 m- 4.6 m) two-span, composite design, laboratory structure, to subject the structure to thermal loading, and to correlate the experimental temperature distributions, strain distributions, and deflections with those obtained from the theoretical study. Infrared heat lamps were used to obtain steady-state thermal loading.

Three theoretical cases were considered for strain calculations: a) both the slab and the beam in plane stress, b) the slab in plane strain and the beam in plane stress, and c) the slab in some state between plane stress and plane strain (partially restrained) and the beam in plane stress. The experimental and theoretical temperature distributions, strains, and deflections were in reasonable agreement.

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 realistic temperature profiles, material properties, and substructure stiffness characteristics"--Abstract, page ii.
