Real-time structural health monitoring
What is SHARD?
The top left side of SHARD shows sensor locations and sensor status information as data quality and exceedance level. Also epicentral distance and seismic wave arrival times are shown. The top right side shows the latest earthquake information in the area of interest and the location of the structure.
Response spectra with 5% damping are calculated in real-time being compared with spectra derived from national design codes as for example EC8, NEHRP or DIN4149. In case of exceedance incidents are generated and red signal is shown. Quality is displayed in the sensor bar as well as channel widget.
The incident heat map gives an instant overview to the occurance history of earthquakes, exceedances and data quality. The intensity of the color correlates with the number of incidents in the time interval. The higher the number of incidents the higher the intensity of the color.
gempa GmbH offers a strong motion processing package fulfilling the task of realt-time structural health monitoring as well as offline analysis.
While SHARD is performing the real-time structural health monitoring the strong motion processing package is complemented by the following modules:
CAPS is a multi format acquisition server allowing to import data not only of seismic sensor, but also of temperature, video and other sensors.
SMGUI is a GUI to perform offline processing of strong motion data for engineering seismology.
Traditional earthquake engineering parameters like:
The strong motion package also comes with an earthquake reporting engine giving the most important earthquake engineering parameter including waveforms and response spectra plots.
