Structural Health Monitoring


Monitoring of structures provides valuable and timely data that, in return, helps building and maintaining sustainable and resilient structural assets. Increasing availability of high-tech monitoring equipment makes possible to monitor the health of structures with high performance.

 Structural Health Monitoring (SHM) can provide insides for the:

  • Gradual change in overall structural parameters and decline of the structure
  • Time-dependent changes in structural components such as expansion joints, bearing, and isolators
  • Response of the structure to extreme events such as earthquakes, strong winds, explosions or accidents

What Monitoring Does?

 Monitoring provides real-time data in terms of engineering parameters such as:

  • Accelerations,
  • Displacements,
  • Humidity,
  • Temperature etc

Accelerations are useful to provide data for the response of the structure to vibrations such as winds, earthquakes or traffic. Low-amplitude acceleration data can also be used for Operational Modal Analysis (OMA) for determining dynamic characteristics of the structure. Change in stiffness or mass of the structure will immediately show alterations in the OMA results, which makes it a useful tool for determining overall structural status.

Displacements are used for monitoring cracks, moving parts, expansion joints or other deformations. Displacements are the best indicators for structural damage and onset of the damage over a time period.

Structures are responsive to humidity and temperature changes, thus environmental conditions should also be recorded together with the structural response data.


Our Services

 Our services in structural monitoring cover a wide range of applications. We can provide services for one-time monitoring applications for:

  • Operational modal analysis,
  • Condition assessment,
  • Proof-tests for design verification.

Furthermore, we can also provide long-term monitoring with permanently installed equipment for

  • Crack monitoring,
  • Deformation monitoring (expansion joints, bearings, dampers, etc),
  • Seismic monitoring for weak and strong ground motions,
  • Structural check after small-to-medium intensity earthquakes,
  • Regular reporting of structural condition.
