In order to continuously track a structure's health, Structural Health Monitoring has been devised and put into practise. Real-time data is collected utilising sensors. Applications for SHM use a variety of wired and wireless sensors, which are constantly improved and upgraded. Load cells, LVDTs, fibre optic sensors, vibrating wire transducers, strain gauges, temperature sensors, tilt metres, and other sensor types are among the many types of sensors utilised for SHM. The main players in the sensor development for SHM concentrate on integrating cutting-edge technology to gather more precise data for improved structure analysis.
By substituting condition-based maintenance for routine and periodic maintenance inspections, Structural Health Monitoring (SHM) lessens the reliance on labor-based care. Additionally, visual aids and non-destructive tests were formerly used to examine the state of a structure (NDT). These techniques have drawbacks, like the optical reach's constrained range, inconsistent testing, the inability to detect potential threats, and others.SHM makes use of sensors to gather and process data at various points throughout the structure's service life. This helps in determining how much the system has been damaged or deteriorated and in receiving that information. Additionally, this aids in figuring out the building's repair and maintenance needs in order to prevent irreparable structural damage and, consequently, accidents.
