Instrumented based bridge evaluation
Bridges in North America are aging and need repair or replacement. Precise evaluation of load carrying capacity of bridges is a way to prevent economic and environmental impact due to replacement and repairs. Current method of evaluation requires the evaluator to make conservative assumptions on load and resistance of bridges. In recent years as technology develops, more precise data can be collected and be processed. Sensors can be mounted at carefully selected positions on bridges to provide sufficient data for more precise bridge evaluation. In this work, available data from long-term monitoring of two bridges will be used to investigate the impact of instrumentation and structural monitoring on the structural performance and evaluation of bridges.
