Structural Health Monitoring [SHM] with Structural System Assessment; Feature- Extraction and Data-Compression for Structural-Systems and Components.
In general, after extreme events, such as Earthquakes, Impact,- Blast Loading, among others, Structural Health Monitoring [SHM] can be utilized for very rapid condition screening, providing near real time information, with respect to the structural integrity of the subject structure or building system. Therefore, typical techniques utilized in the field of Structural Health Monitoring [SHM] are Wave-Propagation based techniques, and Vibration based techniques. Oftentimes, it is of great help to develop an initial understanding of the parameters that are sensitive to the expected damage, so that the “flawed-system” can be introduced and utilized to validate that the diagnostic measurements are sensitive enough to distinguish between features identified from the undamaged and damaged structural system.
The use of analytical tools, such as experimentally-validated Finite Element Models and/or Boundary Element Models, can be a great asset in this process. Which one or more than one, do you prefer to use for Structural Systems (Buildings, Bridges, Specialty Structures) and why?
