摘要：	This report discusses the planning, design and installation of monitoring systems on a network of bridges in the State of Connecticut. The project began with the development of a generic set of guidelines for using currently available monitoring equipment to serve as a basis for designing long-term systems for each of the different bridges. These were then used to design individual monitoring systems that were tailored to each bridge, using sensors for strain, temperature, tilt and vibration. Monitoring has been conducted on a continuous basis, with excitation provided by normal traffic loading. Results from the four fully operational monitored bridges are presented. The goal has been to use long-term monitoring to learn how bridges behave over many years and to use data from the monitoring systems to establish a basis for long-term structural health monitoring. Systems for five additional bridges are planned or under construction. / NOTE: Final rept.
