Industrial structures

Dynamic finite element analysis of structures to determine:

• Natural frequencies and mode shapes
• Steady-state dynamic response to harmonic excitation
• Transient dynamic response to events such as start-up
• Frequency response analysis for stochastic vibrations
• Spectrum response analysis for seismic loading
• Structural velocities and accelerations

The results from the above finite element analyses can be assessed for various objectives, such as:

• Design fatigue life
• Human exposure to vibration
• Vibration limits to which mounted machinery will be exposed
• Serviceability requirements
• Ultimate strength in the case of seismic loading
