Seismic qualification via FEM

Seismic qualification via FEM

Calculating the strength of mechanical structures under seismic loads

The security and serviceability of plants and assemblies in earthquake-prone areas requires proof of stability, integrity and reliability of devices and components under earthquake-specific loads.

 

Benefits of calculated analyses

  • Valuable input at an early stage in the design phase
  • Component optimisation
  • Complete strength evaluation or calculated evaluation as supplement to the acceptance test
  • Cost-efficient comparison of the impact of different response spectrums
  • Early strength evaluation for new products by applying updated FE model properties from previous projects
