Structural vibrations

For the dynamic analysis of civil structures, D2S International proposes a innovative approach, that combines experimental and numerical analyses for an optimised design.

 

Experimental analyses:

  • measurement of stresses;
  • measurement of vibrational levels;
  • experimental modal analysis;
  • signature analysis;
  • specific vibrational measurements: impedance of piles, vibrational levels during driving of piles in the soil;
  • vibrational monitoring of sensitive areas to external sources (construction work, … ).

Numerical analyses:

  • structural modeling of structures & buildings using finite element methods to calculate their vibrational behavior, leading to an optimized dynamic behavior: less vibrations, improved life time and reduced stress levels.
  • design of seismic and anti-vibrational foundations of industrial (paper mills, crushers, vibrating screens, …) and laboratory buildings (micro-electronics, research labs, …)
