RR527 - Fluid structure interaction effects on and dynamic response of pressure vessels and tanks subjected to dynamic loading

As part of a suite of work looking at fluid interaction effects on (and the dynamic response of ) pressure vessels and tanks subjected to dynamic loading, this report details the findings of a state-of-the-art review of the available literature, to consider analysis methodologies, dynamic loads and simplified procedures for the determination of the response of tanks and pressure vessels subjected to strong vibration. Strong vibration is defined as the shaking of a structure resulting from earthquake, blast or ship impact. The response of a tank/vessel under strong vibration can be split into three hydrodynamic components and simplified procedures exist for determining the response of fixed-base, vertical, cylindrical tanks/vessels. For other tank/vessel types, linear/non-linear finite element dynamic analyses need to be used, as no simple solution for the various hydrodynamic components are available.
