Significance of Structural Health Monitoring System is Increasing Rapidly as Major R&D activities continue in the U.S.
Any structure requires timely monitoring and inspection, in order to ensure it’s the structural integrity of the building is intact. Structural health monitoring (SHM) refers to the process of implementing damage detection for engineering structures such as buildings and bridges. The SHM process is also essential in estimating performance deterioration of civil infrastructures and detect the evolution of damage. There are different types of equipment and sensors used in the SHM process that help to monitor the structural health of the building. For instance, an accelerometer is an electromechanical device used for measuring acceleration forces through single or multi-axis directions.
A system of SHM applications typically consists of sensors that
collect data related to changes in structure and the state of its materials.
The data collected from these sensors are then processed by computer
algorithms. Analysis results are reported to the company that owns the
building, which can then use the information to make a determination about the
condition of the building. The analysis provides important insights into the
structural health of a building and the ability to perform repairs. Some
applications use infrared technology to detect changes in the health of a structure.
Furthermore, some of the applications include acoustic wave energy, ionization,
and thermal imaging. By comparing structural health data with architectural
drawings and plans, a company can determine problems and take corrective
action.
Many companies in the U.S. are focused on developing innovative
systems to monitor and structural integrity of bridges and other civil
infrastructures. A bridge health
monitoring system (BHMS) has been developed, which is a new and
cost-effective approach to structural health monitoring. According to the CNN
report from February 2018, around 54,249 bridges in the U.S. are rated as
structurally deficient and hence require SHM operations. BHSM can help in
monitoring and assessing the structural integrity of these bridges and help
detect damages. This a sensor-based SHM, which provides data via the cloud,
making it cost-efficient. Governments of many states have started adopting such
systems and will witness massive adoption in the near future.
