ANALYSIS AND FATIGUE: SEISMIC QUALIFICATION

Detailed seismic qualification is possible using the techniques of Finite Element Analysis. The seismic qualification of a support stand for an automatic control valve in an industrial process was critical for the safety of workers in the event of an earthquake. Finite Element Analysis methods and modal analysis was performed in order to ensure the integrity of the component and the attached piping.

Once the system was accurately modeled, a simulation of a typical earthquake was possible, allowing the design to be qualified.

With increasing degrees of system complexity, Finite Element Analysis techniques become an important step in seismic design and qualification.
