Effect of the Extension of Basement Floor and the Importance of a Proper Design of Interaction between the Foundation and the Subsoil

Abstract

Proper design of structural system is the most important task for a structural engineer. Correct assessment of interaction of the building with the subsoil and its significant impact not only on the foundation structure but also on the entire building is very often forgotten. For design of all parts and for the whole structure the ultimate limit state (ULS) and serviceability limit state (SLS) are crucial. Static and dynamic analysis of the building has presently became an inevitable part of the design of difficult structure. In this paper both the changes, which are visible by the variations of the structural system, and the way of the foundation and necessity of knowing the properties of the foundation soil have been presented. Proper design of the interaction between the building and the subsoil is very difficult problem and therefore it is very important for experts to cooperate, mainly for structural engineer and geologist.

Calculation of Characteristics Describing the Properties of Dynamical Systems

“…It is possible to compute them in several ways, e.g., to use the Fourier transform for the transmission from time to frequency domain. Using of presented technique is possible when solving various dynamical problems [4][5][6][7][8][9]. From the presented results it can be seen that values of dominant frequencies are f (1) = 4,04 Hz, f (2) ACKNOWLEDGMENT This work was supported by the Grant National Agency VEGA of the Slovak Republic, project number 1/0005/16.…”

Frequency characteristics of a dynamical system at force excitation

“…They can be calculated in various ways, for example by the passage from time to the frequency domain on the basis of the Fourier transform. The usage of derivative procedures can be adopted to solve a wide variety of dynamic tasks [4], [5], [6], [7]. …”

The Possible Causes of Damage to Concrete Tanks, Numerical Experiment of Fluid-Structure-Soil Interaction

“…The seismic design of liquid storage tanks has been adopted in [1][2][3][4][5][6][7]. The problem of fluid-structure interaction is very important in case of high tanks.…”
