Sensequake is a world leader in structural health monitoring and seismic assessment for buildings, bridges and infrastructure. We have developed state-of-the-art software and sensors to provide professional services and a turnkey solution to engineers, governments, insurance firms and the real estate industry.
Our patented technology performs structural health monitoring and seismic assessment solely based on actual data from highly sensitive vibration sensors - saving time, effort and money - all while providing superior results. By doing so, a smart database is created which can be used for determining structural changes over time. This allows for the detection of hidden defects, undocumented structural modifications and integrity concerns not detected by visual inspection and traditional engineering practices which can significantly improve disaster preparedness and recovery plans. We also provide specialized periodic or permanent structural health monitoring solutions.
Applications of our
Ambient Vibration Test
Find the natural frequencies, modal shapes and the damping ratios to create a baseline
Improving Reliability Of Assumption-Based Models
Calibrate pre-existing finite element models to increase their reliability
Non-Destructive Condition Assessment
Focus on critical locations, examine integrity between structural blocks, structural joints or floor flexibility
Track long-term vibrations. Especially useful near construction sites or for highly sensitive equipment / structures
Monitor a structure's modal properties periodically or permanently to detect hidden changes
Run time-history analyses on
any amount of ground motions to
provide the response histories and
maximum global seismic demands
without finite element models
Supply response spectra at any building location to provide further component-level damage evaluations
Compare the generated seismic demands with codes such as FEMA P58 to generate repair time and damage cost estimates
Increased reliability and accuracy
No need for detailed engineering plans and assumptions
Rapid seismic assessment
Optimized retrofit schemes for more reliable and cost-efficient structures
Results based on actual data from sensors
No need for finite element models
"Ambient noise study proved to be a very efficient tool for the seismic response evaluation of the Centre Block, a primary heritage building of the Canadian Parliamentary Precinct in Ottawa. It highlighted, at an early stage, several aspects of the building response to seismic loads, aspects which will require special consideration during the design phase. At the same time, the ambient noise study was used for the calibration of the seismic analysis computer model developed by the structural consultants. Sensequake provided timely professional services for the test planning, data collecting and post-processing, working diligently on a very complex structural framing and many site constraints."

"Sensquake direct sensing-based seismic evaluation of structural and non-structural components rather than finite element models helped us to identify the most vulnerable locations in the building and calibrate our finite element models to design the most reliable retrofit scheme. In one of our major projects, the technology detected structural characteristics and floor in-plane flexibility that was not visible through traditional methodologies.
This technology will allow our customers to establish a smart database of their existing portfolio of structures allowing them to accurately monitor any changes in the future and cost-efficiently optimize retrofit plans across their portfolio. We look forward to working with Sensequake again."
"The technology advantage presented by Sensequake is revolutionary. Their approach dramatically improves the viability of conducting asset portfolio seismic assessments, both from an initial and ongoing assessment point of view. Their ability to assess a facility regardless of its age and the state of its documentation in a non-destructive and non-intrusive manner is critically important. Their ability to integrate their results with a structural finite element model ensures that this model is realistic and that this model has been cost-optimized for the required performance."
