Structural Health and Response Monitoring is an innovative method of monitoring structural status and performance without otherwise affecting the structure itself. Structural Health and Response Monitoring utilises several types of sensors embedded in, or attached to a structure to detect exceedance of allowed performance criteria as well as identify and verify structural behaviour.
The strength and serviceability of a structure can be considerably reduced by natural or human-made events, and increased levels of use.
Utilising Structural Health and Response Monitoring systems, timely notifications about any potential problems can be generated and behaviour of the structure can be monitored.
The emerging use of Structural Health and Response Monitoring especially in the last decade, is a result of the increasing need for the monitoring of innovative designs and materials as well as a better management of existing structures.
Consider a typical office building with up to 500 people working in it. After a substantial natural or manmade disaster; the building’s owners would typically need to have a structural safety survey done before allowing the office workers back in to the building.
The process can take from many hours to a number of days depending on the size of the building and the suspected damage.
However, had the proprietor installed a live monitoring system; he would have been able to instantly say whether the safety levels had been breached. What is the cost of the survey? What is the cost of lost time due to 500 office workers being idle?
Earthquakes are perilous and inevitable natural events, causing severe damage and loss of life. There is no proven method to forecast the precise occurrence time of an earthquake nor its location or size. Yet, utilising state of the art scientific methodologies as done in GeoSIG Earthquake Early Warning (EEW) solution, it is now possible to quite accurately assess the location and size as soon as an earthquake emerges using its non- destructive primary waves. Thus, warnings about a potential strong shaking can be generated almost instantaneously , until destructive secondary seismic waves arrive.
Based on fast and reliable communication channels, this provides the crucial seconds to take measures which may help reduce catastrophic impacts of seismic events.
After an earthquake, GeoSIG Rapid Response (RR) solution provides analytic and thematic information on the aftermath of the earthquake in terms of shake maps consisting of observed ground motion parameters as well as estimated damage distribution.
