Integral Abutment Bridges

In an integral abutment bridge, thermal expansion and contraction is absorbed by the piles supporting the abutment instead of expansion joints. In this project, integral abutments are instrumented with strain gages installed on the piles of various bridges at locations throughout Illinois at 8 different depths to observe the stresses induced by expansion and contraction. Other gages were mounted in the deck, on girders, and at the interface between the abutment and abutment diaphram where gages are installed on the vertical reinforcement bars. Additional study will include improvement of present designs to decrease cyclic stresses sustained by pilings and abutment diaphragm.
