摘要：	This report deals with Phase One of Texas Department of Transportation (TxDOT) Project 1304 (Behavior of Elastomeric Bearings). The overall objectives of that project are: (1) to recommend procedures for designing elastomeric bearings used by TxDOT and (2) to recommend practical guidelines and procedures for inspecting existing and future elastomeric bearings. The overall objectives of Phase One of that project are: to verify field reports; to conduct field surveys; and to document bearing and girder movements. To accomplish the Phase One objectives, the following tasks were carried out: a comprehensive literature review was conducted; field reports were verified by site visits (Slaughter Creek, Beaumont, Paris, and Alanreed) and by coordination with the BRINSAP database; two bridges were selected for field instrumentation and study (Slaughter Creek and Alanreed) with emphasis on bearing and girder movement; and the BRINSAP database was used to identify bridges that might have bearing problems.
