Basic concepts about application of dual vibration absorbers to seismic design of nuclear piping systems
Abstract
The design value of damping for nuclear piping systems is a vital parameter in ensuring safety in nuclear plants during large earthquakes. Many experiments and on-site tests have been undertaken in nuclear-industry developed countries to determine rational design values. However damping value in nuclear piping systems is so strongly influenced by many piping parameters that it shows a tremendous dispersion in its experimental values. We, thus, still confront with difficulty not only in clarifying damping characteristies but also in obtaining high design damping value.
