As a supplementto a recently reported study, thehydrodynamicwallpressures and theassociated tankforces inducedby horizontal groundshakingina rigid, vertical, circular cylindrical tank containing liquid layers of different thicknesses and mass densities areexamined, and comprehensive numerical solutions arepresented fortwolayered and some three-layered systemswhichelucidate theunderlying response mechanismsand the effects ofthe various parameters involved. Both the impulsive and convective actions arestudied. Additionally, solutions arepresented formulti-layered systemsapproximating a liquid withan exponential, continuous variation indensity, and theinterrelationship ofthesolutions forthecontinuous systemand its discretized, layered approximation isdiscussed.
