Magic R Seismic Design of Water Tanks

The inferred R (in the 1978 code) varies whether or not the tank is anchored or unanchored.This is a direct result of the 2.5 (unanchored) and 2.0 (anchored) multipliers that the 1978 code authors used,which was geared to penalize unanchored tanks (i.e.,require a higher base shear force for design).Once we convert the 1978 base shearJak niezakotwione zbiorniki magazynowe cieczy zachowuj Especially tank-base uplift provisions proposed by the current codes such as API 650 and Eurocode 8 are based on a mechanical spring-mass analogy,but this aproach has very little technical verification for unanchored tanks.The tank base plate uplift is a function of tank size,tank aspect ratio (liquid height to tank diameter ratio),tank Jak niezakotwione zbiorniki magazynowe cieczy zachowuj Especially tank-base uplift provisions proposed by the current codes such as API 650 and Eurocode 8 are based on a mechanical spring-mass analogy,but this aproach has very little technical verification for unanchored tanks.The tank base plate uplift is a function of tank size,tank aspect ratio (liquid height to tank diameter ratio),tank
