Beitrag zur Berechnung von nachgiebig gelagerten Behältertragwerken unter seismischen Einwirkungen
In order to take into account effects of interaction between storage tank, liquid and soil under the influence of a seismic impact an approach often taken in practical construction analysis is the use of so-called engineering methods. These are based on simple mechanical models and take advantage of the sub-structure method to consider structure-soil-interaction. In the paper, modal analysis of the interaction motion of liquid and tank shell is dealt with by the integration equation method. This is applied for examination of the behaviour of the ideal liquid as well as the influence of the compressibility of the liquid. A model is developed in order to take into account the viscosity of the liquid from which damping factors for the motion of the liquid surface are derived. Impedance functions are defined to consider the foundation of the tank depending on the flexibility of the foundation. Damping values and changes in frequency are calculated from the complete system consisting of storage tank, liquid and soil, which are intended for the application in calculation concepts suitable for official design specifications.
