AN OVERVIEW OF STRUCTURAL HEALTH MONITORING BY USING SMART SENSING TECHNOLOGY – “A REVIEW”

Abstract

In the present growing technology, the continuous monitoring of structures has been easier
task by using the various sensor techniques and Internet of Things technology to ensure the
safety and strength of the structures. All the structures will get degrade and deteriorate with
increase in time due to loadings, corrosion and other factors. To implement the continuous
monitoring system for the structures, the Sensors are plays major role for the monitoring
process. Due to various continuous environment and climatic changes, the strength and
durability of the structures are severely affected and the damage deduction inside the concrete
structure is becomes a very monotonous process. The various non destructive testing methods
were used to find the strength, damage and durability assessment in the existing and proposed
concrete structures. In the destructive testing methods, the assessment is carried out near by
the concrete damaged structures by direct contact which may cause adverse effect. By using
modern technology, nowadays non destructive and non contact methods have been
implementing to deduct the various parameters of the concrete structures by using modern
sensors. This review paper gives the overview about the sensors and explains the various
practical applications of sensors in the concrete structures to identify the problems by using
modern sensors like piezoelectric sensor, Wireless sensor, and smart aggregate to deduct the
concrete strength, rate of corrosion, cracks, and strain deflection of the structures
