Sherborne Sensors’ Mike Baker examines how field-proven sensor technology lies at the heart of Structural Health Monitoring (SHM) innovation.
Structural Health Monitoring (SHM) is an emerging field that provides information on demand about any significant change or damage occurring in a structure. It has been employed for many years in civil infrastructure in various forms, ranging from visual observation and assessment of structural condition, to technology-led approaches involving deployment of an array of sensors that can include accelerometers, inclinometers and strain measurement devices on site. These sensors can be deployed on a permanent basis or moved on and off site each time a fresh set of data is required.
Conventional forms of inspection and monitoring are only as good as their ability to uncover potential issues in a timely manner. One of the major difficulties with SHM instruments for example, is managing the huge volumes of data that sensor arrays generate. Meanwhile, visual inspections and evaluations are insufficient for determining the structural adequacy of bridges or buildings.
