Abstract

There are approximately 600,000 bridges in the United State. Of the 600,000 bridges, 12% are deemed structurally deficient and 13% are declared functionally obsolete. Traditional inspection methods and technologies are not effective in detecting onset of deterioration. The need is an effective, continuous monitoring system to identify bridge deterioration at early stages to take effective and efficient maintenance decisions. The computer simulation models in conjunction with continuous monitoring data can be used to develop stress signatures specific to various deterioration types. The stress signatures can be used to identify the type of distress and to initiate corrective measures immediately to extend bridge service life and to eliminate costly repairs or replacements.
