Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   Full-scale measurements are a vital component of our program to advance understanding of wind effects on transportation structures. Such measurements provide detailed information on site wind conditions and structural behavior that is not available from any other source. They aid in the design of and serve to validate simulations in the laboratory. Full-scale measurements can provide a means to calibrate the results of numerical predictions or computational simulations. They can also be used to diagnose wind-related structural problems and to evaluate the effectiveness of aerodynamic retrofits made to bridges. Historically, field tests have consistently been a highly productive way to advance our understanding of the interaction of loads with structures.
Goals:   The objective of this study is to continue a vital program of field testing and monitoring of select structures to further clarify wind/structure interaction issues, advance techniques for evaluating and predicting structural behavior, evaluating the effectiveness of new designs and retrofit countermeasures.
Product Type:   Research report
Test Methodology:   Currently, two bridges are being monitored; one for the long term and one for the short term. The instrumentation systems deployed operate autonomously, but are supervised remotely from Turner-Fairbank Highway Research Center. Wind and weather conditions are measured by anemometers and other meteorological sensors, while bridge behavior is measured primarily by accelerometers. Bridge sites will be dropped and others will be added as appropriate and as opportunities arise.
Other Information:   Bridge access and logistical support are provided by the Maine Department of Transportation and the┬áLouisiana Department of Transportation as needed.
Expected Benefits:   Clarification of structural performance problems and site wind conditions, validation of small scale wind tunnel studies and predictions as well as computational simulations, evaluation of mitigation measures.
