Abstract
The main objective of this research was to study and evaluate the effects of thermal movements on integral abutment bridges during early construction stages. Particular emphasis was placed on the evaluation of the resultant state of stress of the upper portion of the steel piling and portions of the girders immediately adjoining the integral abutment. A full-scale model representing the end portion of a typical highway bridge was constructed and tested in two stages: a) After the girders were erected and welded to the bearing piles, but before the integral abutment concrete was poured. b) After the integral abutment was built and the concrete attained its design strength. The test specimen was subjected to a series of predetermined longitudinal movements simulating expansion and contraction due to temperature changes. These movements were applied via hydraulic jacks positioned between a stationary jacking abutment and the girders. The 25-foot span length and the location of the jacks at the neutral axis of the girders provided a representative stress distribution at the sections investigated.
