Ambient vibration tests allow for an in depth analysis of structures.

Our structural testing method is non-destructive and rapid and can give a lot of crucial information pertaining to the structure. Using our highly sensitive Larzé sensors and 3D-SAM software, the frequencies, mode shapes and damping ratios can be extracted and determined directly from a physical, on-site test without the need for creating complex models or having detailed knowledge of the building. The process gives an in-depth look at the structure at that point in time and can be used to compare the future health of the a structure. This can be used to calibrate numerical models, find hidden defects within the structure or used to periodically monitor the structure's health as it ages or if damage occurs.

   •   Simplified ambient vibration test

   •   Derivation of main modes, natural frequencies, mode

       shapes and damping ratios

   •   This test creates a baseline that may be used for

       future comparisons and structural health monitoring

   •   Obtained data can be used to calibrate finite element

       models in order to increase their reliability and create

       more cost-efficient retrofit schemes

   •   Accurate natural frequency derivation

   •   Mode shape rendering and damping ratio derivation

   •   Accurate derivation of higher modes and torsional

       modes of irregular structures

   •   This test creates a baseline that may be used for

       future comparisions and structural health monitoring

   •   Detailed report of findings by our team of experts

   •   Obtained data can be used to calibrate finite element

       models in order to increase their reliability and create

       more cost-efficient retrofit schemes

Our technology can be applied to highly specific projects:

   •   Assessing in-plane flexibility of building floors and

       roofs

   •   Specialized analysis for specific structural

       components such as joints to understand the true

       behaviour of the structure

   •   Identify integrity discontinuity within structures or

       between structural blocks

    •  Evaluating the required net-gap between

       structural blocks to mitigate the seismic impact

       hazard

   •   Lateral stiffness derivation per story

   •   Detection of soft-stories

   •   Find resonance frequencies of floors and

       machinery to mitigate excessive floor vibrations

   •   Modal analysis of walls for blast-tests
