A Review on Structural Health Monitoring using NDT

Any structure is always designed as per the IS regulations and Standards; however they are always not followed during the actual construction process. This tends to symptoms such as deterioration and prompting early restoration and repair work. The corrosion of the RCC structures is always considered as one of the major concern hence periodic monitoring and maintenance is mandatory. Over the period of time as the structure gets older, it exhibits the distress in the form of cracking, delamination, corrosion, fracturing etc. To prevent such causalities and anticipate preventive measures structural health monitoring is one of the essential step. These deteriorated structures can be rehabilitated using various forms of admixtures and new materials for the repair. Non-destructive Testing (NDT) has been used to assess the structure’s properties and is useful in the inspection and monitoring of existing structures.
