The conservation of seismic analysis and design of piping systems due to analysis methodologies and damping values was quantified. Envelope response spectrum analyses, independent support motion response analyses, and multi-support time history analysis methodologies were evaluated. Constant damping, ranging from 1% to 10%, and PVRC damping were considered. Conservatisms were evaluated with respect to best estimate response of the entire seismic analysis chain and of the piping system alone. 18 refs., 15 figs., 10 tabs.
