A Brief Review on Smart Structural Health Monitoring Technologies

Abstract

Structural Health Monitoring (SHM) is a method to determine the current status of the structure and the damages in the structural elements with minimum labour involvement. Structural health deteriorates over time and depends on loading on the structure and environmental conditions. Therefore, SHM is essential for safety and durability of structures. This chapter deals with different sensing methods like Global Positioning System (GPS) and Internet of Things (IoT) for monitoring the structural health. Application of different sensors like fibre optic sensors, magneto-strictive sensors, piezoelectric sensors and self-diagnosing fibre reinforced composites is involved in the smart sensing technologies. Their merits and demerits of are also mentioned in this chapter.
