Book Description
This project investigated the seasonal behavior of integral abutment bridges through field monitoring and finite element modeling (FEM). The Orange-Wendell Bridge was used as a case study for the project. The structure was instrumented with 85 gages measuring bridge movements and forces (temperature gages, joint meters, tilt meters, strain gages, earth pressure cells, thermistors and four inclinometer casings for manual readings). Instruments were monitored by the University of Massachusetts at Amherst from January 2002 through December 2004. Both 2-D and 3-D FEM of the bridge were developed using GTSTRUDL and calibrated to the field data. Parametric FEM was performed to evaluate the influence of soil properties and construction practices on bridge behavior.

Book Description
Integral abutment bridges, a type of jointless bridge, are the construction option of choice when designing highway bridges in many parts of the country. Rather than providing an expansion joint to separate the substructure from the superstructure to account to volumetric strains, an integral abutment bridge is constructed so the superstructure and substructure are continuous. The abutment is supported by a single row of piles which must account for the longitudinal movement previously accommodated by the joints. The primary advantage of an integral abutment bridge is that it is jointless (expansion joints are eliminated) and thus reduces both upfront and overall life-cycle costs. In addition to other benefits provided by integral construction, the reduction in overall cost has led to INDOT requiring all new structures within certain geometric limitation be integral. These geometric limitations, traditionally based on engineering judgment, have been modified over time based as investigations have revealed more about the behavior of integral abutment bridges. While there has been a considerable amount of research and investigation conducted on the behavior of integral abutment bridges, information is limited on both long-term behavior and the effects of highly skewed structures. Because there is a great desire for the application of these structures to be expanded, this research serves to expand the understanding of the behavior of integral abutment structures. Additionally, updated geometric limitations are recommended along with design recommendations and recommended analysis procedures for properly modeling integral abutment behavior.

Book Description
This report presents findings of a literature review, a field trip, and a finite element analysis pertaining to integral bridges. The purpose of the report is to identify problems and uncertainties, and to gain insight into the interactions between the foundation piles, the integral abutment, and the surrounding ground. The field trip included visits to six bridges arranged by Mr. Park Thompson from the Staunton district. Pertinent literature is reviewed and findings are presented. Important factors identified on the basis of this review are settlement of the approach fill, loads on the abutment piles, the nature of the abutment displacements and the associated earth pressure distribution, secondary loads on the superstructure, and soil structure interaction effects. The causes of approach fill settlement and possible mitigation techniques are discussed. Recommendations for improving the performance of integral bridges are included, and actions for improvement of integral bridge behavior are suggested.
