摘要：

A sound understanding of a structure's normal condition, including its response to normal environmental and operational variations is desirable for structural health monitoring and necessary for performance monitoring of civil structures. The current paper outlines the extensive monitoring campaign of the Tamar Suspension Bridge as well as analysis carried out in an attempt to understand the bridge's normal condition. Specifically the effects of temperature, traffic loading and wind speed on the structure's dynamic response are investigated. Finally, initial steps towards the development of a structural health monitoring system for the Tamar Bridge are addressed. (c) 2012 Elsevier Ltd. All rights reserved.
