The Michigan Geotechnical Seminar Series is sponsored by:
Elimination of the bearings and expansion joints in the superstructure of
integral abutment bridges offers the advantage of reducing the initial and life cycle
costs of the structure. Due to the thermal expansion/contraction cycles of the bridge
deck such elimination may result in an adverse effect on the displacement demand at
the pile-abutment connection and on the earth pressures acting on the abutment wall.
This research consisted of analysis of the problem by considering soil-structure
interaction. The approach was multifaceted as it included experimental and numerical
analysis. The experiments consisted of
laboratory tests and large-scale tests, as
well as data analysis of monitored full-
scale bridges in Indiana. A new soil
constitutive model was developed as part
of the study. The model was validated
and calibrated based on the laboratory
and field experiments, and then used as
part of a parametric analysis to provide
recommendations for the design of
integral abutment bridges
