Technology and application of structural health monitoring in bridges

Structural Health Monitoring (SHM) has become a useful tool for detecting when the characteristics of a structure have changed to indicate damage such that well-timed and effective maintenance may be planned and the remaining performance capacity may be assessed. SHM has also lead to a better understanding of the loads and the response within a structure in order to optimize future design. In this paper, research is compiled on the current practice of SHM with coverage of sensors used, system configurations, data management, analysis and a discussion of current issues. Recommendations on the current state and future of SHM are made and case studies investigate recent applications. A proposed procedure for the design and implementation of a SHM system is examined and then applied to the design project for the Master of Engineering program in High Performance Structures at MIT. Conclusions include a suggestion on the most effective way to design a SHM system, what the industry needs to mature and predictions of the future of the industry.
