Abstract

The purpose of structural health monitoring is to provide information by making a simultaneous diagnosis of the status of the structure. Despite aging, environmental conditions and unforeseen circumstances, the construction should remain as specified in the design. Changing the environmental conditions causes the sensor and the host structure to change material properties. It is essential to take into account environmental conditions to prevent misdiagnosis. Therefore, the real cause of the change can be determined.
