Seismic Analysis of Integral Abutment Bridges Considering Soil-Structure Interaction
Integral abutment bridges are single or multiple span bridges with the superstructure cast integrally with the substructure and designed without any expansion joints in the bridge deck. These bridges are usually designed to spread the stiffness and flexibility throughout the structure and the soil so that all supports accommodate the loads. These bridges usually include capped pile stub abutments. The piers are typically constructed in such a way that they may be cast either integrally with or independent of the superstructure. Semi-integral bridges are single or multiple span continuous bridges with rigid, non-integral foundations and movement systems primarily composed of integral end diaphragms, compressible backfill, and movable bearings in a horizontal joint at the superstructure abutment interface. The first integral bridge was built in 1938 at the Teens Run Bridge in Ohio in the United States. It consisted of five continuous reinforced concrete slab spans supported by capped pile piers and abutments. The construction of integral bridges has since spread throughout the United States and abroad.
