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
