Structural Health Monitoring is monitoring a structure (like a bridge, building or dam} for changes that may indicate damage or degradation of that structure. While the structure is static, it is subjected to dynamic forces; wind will blow over the bridge or against the building, waves will hit the dam or oil platform, cars will also drive across bridges. These dynamic forces will excite vibrations in the structure. The forces excite modes of vibration in the structure and Structural Health Monitoring uses changes in those modes to detect damage or degradation.

Structural Health Monitoring is not as mature of a field as Machinery Health Monitoring and a lot of the SHM activity is still at the university level.

There is a short course on Structural Health Monitoring at Stanford University at the end of this month. Details are available at: http://www.la-dynamics.com/cou...02015/course_shm.htm.
