| Popis: | This paper presents the seismic response of laminated composite cylindrical tank in the framework of the first-order shear deformation theory. A random microstructure of composite material results in transversely isotropic properties at the meso-scale. The analysis of composites with random microstructure is done by using of a fictitious hexagonal microstructure. The laminated representative volume element is assumed for obtaining the effective material properties of the laminated composite. Seismic analysis of liquid storage laminated composite tank is different from the analysis of typical structures. The fluid exerts hydrodynamic impulsive and hydrodynamic convective pressures together with hydrostatic pressure on tank walls and bottom of the ground-supported fluid filling container during an earthquake. The knowledge of pressures and forces acting onto walls and bottom of the container and total hydrodynamic effects of liquid on storage tank during earthquake loading plays fundamental role in the design of an earthquake resistance of fluid filling container. The seismic response of a fluid filling laminated composite container was solved for Slovakia region respecting recommendations of Eurocode 8 Part. 4. We considered only horizontal seismic load by using the elastic response spectrum. |
