Fluid - Structure - Soil Interaction of Cylindrical Liquid Storage Tank Subjected to Horizontal Earthquake Loading
Shallow founded tanks are strategic structures
used to store a variety of kind of liquids. The fluid
develops hydrodynamic effect on solid domain of
container during an earthquake. This paper provides the
theoretical background for numerical model on seismic
response of fluid-structure-soil interaction. The Finite
Element Method (FEM) was used for seismic response of
shallow founded cylindrical container. The Fluid-
Structure-Soil interaction of shallow founded tank was
analysed according to theories of I. Limit States - the
ultimate limit state (ULS) and II. Limit States - the
serviceability limit state (SLS) pursuant to EN 1997-1.
Summary of the results: the maximum rotation of
foundation is growing with the reduction of the stiffness
of the subsoil and the vertical and horizontal bearing
capacity depends on the strength properties of the
subsoil
Strength Tests of Concrete Specimen Exposed to an Aggressive Environments
The paper presents the results of static tests of
the concrete beams exposed to the aggressive environment
in the agricultural building. The long-term effect of an
aggressive environment was expected. The aim of analysis
was to evaluate the condition of the ceiling panels. Static
tests have provided information on the possible modulus of
elasticity and the classes of concrete used to make the
beams. The concrete beams with higher structure porosity
and lower bulk density showed lower strength values and
lower modulus of elasticity values. The knowledge gained
from the analysis of beams will be used for comparison
with the results obtained from the ceiling panels
Parametric simulation of ceiling panels exposed to aggressive environments
The subject matter of the contribution is findings obtained from a parametric simulation of ceiling panels behaviour under a change of determined parameters. The optional parameters included concrete strength, reinforcement cross-section area, and concrete covering. The experiment investigated an impact of the given parameters changes onto the element resistance which was evaluated on the basis of the ultimate state of usability, namely from the point of view of crack checking and deflection measuring. Panel behaviour was presented by a load-deflection relation and crack topograph
Selected findings from parametric studies determining the resistance of concrete panels in real terms
In the article selected results of parametric analysis of lightened reinforced concrete panels used in agricultural objects are presented. The aim of the analysis was to devise a parametric model that can be later on used for the simulation of behaviour of real ceiling panels when changing predefined parameters
