STRUCTURAL HEALTH EVALUATIONS AND MONITORING

Sensequake technology allows for detailed structural integrity assessments

Using the highly sensitive Larzé sensors and 3D-SAM software, tests can be conducted that are non-destructive, only take a few hours, and are based on real data collected from the structure. After detailed analysis, the structural baseline (frequencies, mode shapes and damping ratios) can be extracted and determined.

 

Baseline tests and Sensequake's unique analysis protocols have the following benefits :

  • Based on Sensequake's highly sensitive Larzé sensors

  • Non-destructive testing only takes a few hours during regular operations

  • In-depth data analysis using Sensequake's 3D-SAM software

  • Prove integrity of the structure using real data or detect and locate damage over time

  • Sensequake's analysis protocols are used to compare baseline tests over time as well as with their database of health baseline properties of both buildings and bridges

  • No structural finite-element models or drawings needed

  • In the case of a retrofit, other engineers can use the baseline results to calibrate their theoretical models to reduce cost and increase reliability

These tests provide a detailed look at the structure's as-is integrity and can be used to monitor changes in structural properties over time.

Baseline
Test

   •   Temporary, non-destructive site test during regular

        operations

   •   Followed by in-depth data analysis to extract baselines

       and structural stiffness

   •   Monitor the structural integrity over time and extend

       service life

   •   Comparisons with the Sensequake database of

       healthy baselines of similar structures to detect and

       locate damages or weaknesses

   •   Find hidden defects, undocumented structural

       modifications and integrity concerns not detected by visual

       inspections

   •   Significantly increase the precision and reduce costs of

       engineering models if rehabilitation is needed.

Periodic
Monitoring

   •   Conduct a thorough evaluation of

        baseline properties to assess

        condition over time

   •   Conduct comparative analyses

       between the baselines of similar

       healthy structures

   •   Conduct baseline properties over

       time using different analysis criteria

   •   As baseline properties correlate to

       the stiffness of a structure, changes

       within the baseline can be mapped

       to the physical structure

Permanent

Monitoring

Permanent structural health monitoring solutions using the ShakeLog System can detect damage and assess integrity over time. The system can:

   •   Monitor structural stiffness in real-

       time

   •   Combine A.I. and advanced

       algorithms to detect changes

 

   •   Send alarms when changes are

       detected

   •   Act as seismic instrumentation

   •   Help increase asset safety and

       decrease repair costs over time
