Integral abutments for bridges in seismic regions: Californian practice

Academic Article


  • The use of integral abutments is common in short-span bridges. These bridges have performed well in the regions with low seismicity where total seismic and thermal movements in the superstructure can be accommodated at the abutment by proper detailing. In high seismic zones where superstructure movement due to earthquake far exceeds that due to temperature variations, bridges cannot be economically designed to prevent significant damage to integral abutments. This paper describes the general design practice in California in the use of integral abutments for bridges in seismic regions.
