Synthesis of Technical Information for Jointless Bridge Construction

This report provides a synthesis of the research conducted on integral abutment bridges in order to describe the behavior of bridges utilizing the jointless concept. The report focuses on research conducted on bridges with continuous connections of the slab and girders to the abutment wall, as opposed to semi-integral bridges, which do not have a continuous connection between the girders and the abutment. Furthermore, this report is intended to describe the key variables that affect integral bridge behavior and performance. It is not intended to be a summary of current design practices. As this study will ultimately lead to recommendations for bridge instrumentation programs, it was necessary to structure the report content in this manner. The report highlights key variables that may require consideration in a future instrumentation program. Section headings are as follows: Introduction; Thermal Stress; Creep and Shrinkage Stress; Skew and Curvature; Abutment Wall-Soil Interaction; Pile-Soil Interaction; Flexibility of the Substructure; Alternative Support Systems; Special Considerations for Cyclic Loading; Approaches; Wingwalls; Practical Considerations; Discussion of Literature Synthesis; and Conclusion.
