This report on Autonomous Crack Monitoring (ACM) systems describes the continuing development of systems to monitor the response of cracks for structural health monitoring (SHM) on and near transportation related structures. This development involved continually evolving AC powered digital data loggers (with and without wireless internet connections), special gages wired to the data loggers, new measurement techniques involving structural displacement, and graphical displays for automated reporting and public interpretation. The system may also be applied to strain measurement in critical locations on steel structures such as bridges. |
