Abstract:

This report describes the instrumentation and data acquisition for an eleven span segmental, post-tensioned ; box-girder bridge in Connecticut. Based on a request from the designers, the computer-based remote ; monitoring system was developed to collect temperature data to provide engineers with information for use in ; the evaluation of the long-term behavior and performance of the bridge. The system was used over a five year ; period to determine maximum and minimum temperatures through the box girder cross section and to develop ; thermal gradients in both the vertical and transverse directions. Comparisons have been made with design ; specification provisions and with recommendations proposed by previous researchers. In addition, software ; has been developed to determine the relationship between the daily maximum temperature differences and the ; air temperatures inside the box girder. This approach is also used to develop the relationship between the ; maximum stresses due to temperature differences and the air temperature inside the box girder. The ; monitoring system is currently being upgraded.
