Consideration of local damping mechanisms in modal FEM analysis of piping systems
Abstract
Analyses of piping systems in nuclear power plants for dynamic loading conditions such as earthquakes and aircraft impact are performed mostly by the Response Spectrum Modal Analysis (RSMA) method. First of all the undamped system is uncoupled and then each modal single degree of freedom (SDOF) oscillator is allocated 2 or 3 % critical damping.
