Simulation Methods

used in seismic qualification

Ensuring the stability, integrity and functionality of facilities and assemblies in earthquake-prone regions requires verification under seismic-specific loads. We employ computational methods, such as the Finite Element Method (FEM), to assess the capability of mechanical structures. Your benefits include:

• Support during the early design phase
• Component optimization
• Computational strength assessment
• Possibility of transferring FE model properties from previous projects to new products via model updates
• Cost-effective comparison of the effects of different response spectra

Our Services in Seismic Engineering

• Consulting and development of seismic design concepts
• Derivation of seismic load assumptions from (inter)national standards (IEEE693-2005, KTA 2201.4, DIN EN 1998-1, IEC 980, IEEE 344-2004)
• Computational modal, frequency response, transient and response spectrum (shock response) analyses
• Comparison of FE models on the basis of test results
• Fatigue strength assessment according to current guidelines (e.g. FKM guideline, VDI2230, VDI2014)
• Component and system testing

Emission Monitoring

Room and exhaust air monitoring systems in nuclear facilities must consistently align with current scientific and technological standards, as well as applicable regulations. The transition to decommissioning, or the decommissioning phase itself, often features very unsteady ventilation conditions. These changes necessitate the adaptation or renewal of monitoring systems. Variable airflow rates, shifts in aerosol particle distribution due to dismantling activities or a rigid monitoring system layout that does not accommodate the ddismantling concept are just a few of the challenges.
