Seasonal thermal effects over three years on the shallow abutment of an integral bridge in Glasgow

Instrumentation was installed during the construction of a bridge of about 60m span with a continuous deck and shallow integral abutments at Carmyle Avenue, Glasgow. Abutment performance during its construction and first year in service have been reported previously. This update describes results of the monitoring from February 1995 to January 1998, Seasonal thermal expansion of the deck caused cyclic movements of the abutments and the magnitude of these movements was measured together with the earth pressure developed in the granular backfill behind the abutment.
