Categories of SHM systems

Category from Webb et al. (2015)		Description
1	Sensor deployment studies	Demonstration of the ability of a sensor to measure a parameter of interest and of a communication system to transmit the data to the operators.
2	Anomaly detection	Detection of change in a parameter with time, for example many systems strive to detect natural frequency of vibration and notice changes that may represent a change in stiffness. However, changes can be due to many causes, such as condition, temperature, humidity and live loading.
3	Model validation	A system that aims to compare measured values with predictions from a structural model to quantify whether or not the structure is behaving as expected. The caveat is that structural responses are relative easy to detect, whereas input loads are difficult to quantify.
4	Threshold check	Comparison of measurements with a threshold level, derived at least in part, from a model of structural behaviour, beyond which action should be taken.
5	Damage detection	Detailed investigation to detect the type, location, extent and rate of damage or deterioration at one or more locations.
