KINEMETRICS
These Seismic and Structural Health Monitoring (SSHM) systems should retrieve useful information from monitoring data, namely for analyzing vibrations measured under ambient/operational excitation and during seismic events, and compare the measured dynamic response with the response computed using finite element models.
KMIDam is a technology platform designed to manage your portfolio of dams with real-time information before, during and post-event. Leveraging a combination of smart sensing, modelling, digital twins, and real-time processing tools, KMIDam provides immediate feedback during events, and tracks changes to your structures that may lead to problems over time.
By investing in KMIDam platform solutions, including high-quality equipment, dam owners can obtain clear evidence on the performance and safety conditions of dams.
This case study outlines results for a dam outfitted with the SSHM4Dams solution, which is part of the KMIDam platform.
This solution was implemented on a 130m high double curvature arch dam with a crest length of 300m. In operation for almost 70 years, horizontal cracks appeared in the upper part of the downstream face during the first filling of the reservoir, and concrete swelling was detected in the late 1990s.
The dam was instrumented over a decade ago with a continuous vibrations monitoring system, developed to continuously evaluate dam performance in normal operating conditions and to control the response during seismic events. The monitoring system comprises 16 uniaxial (EpiSensor ES-U2) and 3 triaxial (EpiSensor ES-T) force balance accelerometers from Kinemetrics …click for more
