Field Vibration Testing

Contact ANCO to test civil structures and equipment in the field.  Since 1971 ANCO has performed over 300 field vibration tests worldwide to determine the in-situ dynamic properties of structures.  

Testing structure properties:

  • Concrete gravity and arch dams
  • Nuclear power plant containment and internal equipment
  • Historical buildings being seismically strengthened
  • Offshore oil platforms
  • Bridges
  • Flexible floors in convention centers and stadiums
  • Machine foundations
  • Piping and cable trays systems
  • Conventional plant boiler structures

Testing to clarify issues:

  • Modal property measurement
  • Verification/validation/modification of finite element models
  • Vibration source identification/mitigation
  • Vibration isolation system evaluation/design
  • Seismic margin analysis/qualification
  • Vibration/stress/drift long-term monitoring

Here is shown data of high resolution FFT displacement measurements taken over a 24 hour period during a site survey identifying periodic motor interferences.
