Dynamic interaction between supplementary support steel and a piping system


This paper addresses dynamic interaction effects between piping systems and support steel under seismic loading conditions. Structural parameters of the support steel such as mass, stiffness and damping can have significant effect on amplification of seismic response of a piping system. In this study, effect of damping has been included for a two-degree of freedom system to arrive at a design criterion which, if met, would minimize amplification of the seismic response. Failing to meet this criterion, it is judged that the piping seismic model must include modelling of the support steel.
