Increasing of Fluid Effect on Liquid Storage Laminated Composite Tank During Seismic Excitation

Abstract

This paper presents influence of fluid filling on the increasing of fluid seismic effect on solid of liquid storage tank. The liquid inside of the tank exerts hydrodynamic effect on tank walls and bottom in addition to hydrostatic effect during earthquake. The knowledge of forces acting onto walls and bottom of the container and total hydrodynamic effects of liquid on storage tank during ground motion plays fundamental role in the design of an earthquake resistance of fluid storage container. The seismic response of a fluid filling laminated composite container was solved for region of Slovak Republic respecting recommendations of Eurocode 8 Part. 4. and the laminated representative volume element for obtaining of the of the laminated composite effective material properties. The effective material properties of liquid storage laminated composite tank were obtained by using of a fictitious hexagonal microstructure and the laminated representative volume element at the meso-scale.
