Structural Dynamics Testing

The Structural Dynamics Testing Lab contains the Multi-Axial Simulation Table (MAST), which applies vibration to the base of structures to measure performance and response. The ‘shaker table’ is capable of reproducing the effects of earthquakes, ambient vibrations, wind loading and vehicle vibrations.


  • Multi-axial simulation table (MAST)
    • High performance platform with 6 degrees of freedom controlled by an advanced system to ensure high quality and flexible signal reproduction.
    • Control at the base of the structures is typically used for seismic or other sources of ground vibration, however advanced control is also possible from sensors mounted on the structure itself.
    • 2msq table holds up to 3 tonnes, with accelerations of up to 5g at full capacity, frequencies up to 200Hz and displacements up to +/-200mm.


  • Non-destructive testing (NDT) uses sensors and high-speed acquisition systems to assess structural properties and integrity.
  • Structural health monitoring (SMH) uses a complex arrangement of sensors (accelerometers or ultrasonic sensors) complemented with machine learning or artificial intelligence for data analysis.
  • Dynamic and vibration testing involves high-frequency vibrations through shakers or impact for modal analysis. Various types of specimens including concrete beams, timber piles and composite flooring can be tested by forced vibration (shakers) or impact (hammer) excitations with the responses measured using highly sensitive sensors such as accelerometers and piezoelectric transducers.
