Numerická ilustrace teoretických výsledků pro nelineární semikoercivní nosníkovou úlohu
Sysala, Stanislav
The semi-coercive problem of a beam on a unilateral elastic subsoil of Winkler's type is considered. The aim of this contribution is numerically illustrate some basic results of the problem, which are summarised in the contribution. Concretely, we are interested in dependence of the problem solution on an external load, the error estimates of approximated solutions and the convergence properties of used numerical methods subject to the load.

Analýza spolehlivosti nosníku na pružném podkladu
Marek, Pavel ; Frydrýšek, K.
This paper is focused on the solution of simple beam continually supported by linear elastic foundation (Winkler’s subsoil). The beam is exposed to combination of dead, long lasting and short lasting forces. For the calculation of maximal bending stresses are used analytical methods and probabilistic approaches (SBRA method, Anthill software).

Dynamické chování nosníku s přdpjatou strunou - vliv útlumu
Fischer, Cyril ; Frýba, Ladislav
The beam with an axial force is coupled by an elastic layer of Winkler type with the pretensiled string. It is subjected to a row of moving forces. The theoretical model corresponds to a prestressed bridge. The concrete bridges of this type are the most spread types appearing on both the road and railway bridges of small and medium spans. The governing equations form a coupled set of partial differential equations that are solved using the Fourier and Laplace integral transformations for the undamped case. The numerical solution is examined for the damped case.
