Abstract:

The recent collapse of the I-35W Mississippi River Bridge in Minneapolis has spawned a growing interest in the development of reliable techniques for evaluating the structural integrity of civil infrastructure. Current inspection techniques tailored to vehicular bridges in particular are widely based on short-term or intermittent monitoring schedules. While these techniques have had reasonable success in assessing the structural integrity of bridges, there are unanswered questions about their effectiveness for monitoring sudden adverse structural changes that can lead to catastrophic bridge failure. Structural health monitoring (SHM) is an alternative inspection paradigm that provides the potential for long-term monitoring of integrity of large-scale structures.
