This paper presents the results from the deterministic and probabilistic analysis of the nonsymmetrical wind effects (torsional effects, soil-structure interaction, wind action) to symmetrical high rise buildings. There are analyzed of uncertainties in the wind action to the various symmetrical high rise buildings. The Eurocode requires, that the resistance of structures must be checked to the accidental torsion effects. In the case of probabilistic

This paper describes the reliability analysis of concrete bubbler tower structure for VVER 440 under high internal overpressure. There is showed summary of calculation models and calculation methods for the probability analysis of the structural integrity considering degradation effects and high internal overpressure. The non-linear analysis of the concrete structures was realized. The uncertainties of the loads level (long-time temperature and dead

This paper deals with an elastic and plastic solution of the steel frame under fire loads. The deterministic and probability analysis of the fire resistance of the steel frame is considered. The executed fire resistance analysis of the steel structures is investigated as the influence of temperature, dead loads and live loads. Deterministic analysis is carried out in accordance of EUROCODE requirements. The Simulation-Based Reliability Assessment

This paper describes the reliability analysis of concrete containment for VVER 440 under high internal overpressure. There is showed summary of calculation models and calculation methods for the probability analysis of the structural integrity considering degradation effects and high internal overpressure. The probabilistic structural analysis (PSA) aims at an assessment of the probability of the concrete structure failure under excessive overpressure.

This paper presents results of experimental and numerical analysis of seismic resistance of reinforced concrete coupling system considering the plastic capacity in accordance of standard requirements STN P ENV 1998, PrEN 1998 (2003) and Önorm B4015 (2002). The plastic capacity of the structure can be established by parameter q in the case of the spectral analysis to determine the seismic response. The experience from dynamic analysis of a hospital

In this paper, there are the elastic, plastic and probability application methods for fire resistance analysis of the steel frame presented here. The executed fire resistance analysis of the steel structures is considered as the influence of temperature, dead loads and live loads. In this paper, the probability analysis is considered as the simulation of various loads and material properties of steel by MONTE-CARLO method and by software ANSYS.

In this paper the knowledge from reliability analysis of concrete containment for WWER 440 under high internal overpressure is presented. There is showed summary of calculation models and calculation methods for the probability analysis of the structural integrity in the case of the loss of coolant accident (LOCA). In the case of the analysis PSA 2 level it is necessary to determine the probability of the concrete structure failure under higher overpressure.

This paper deals with bending of reinforcement concrete beam rested on non-linear elastic foundation. The beam is discretized by layered izoparametric finite elements. The deformation of solid soil is modeled with the infinite elements. The beam and foundation connection is considered as the non-linear normal and shear bond. The concrete material is modelled with stiffening in compression and softening in tension. The properties of the steel are

For modelling an unbounded area in many engineering problems (for example, in geomechanics) infinite elements can be used. This paper presents basic information about infinite elements and how a new type of infinite element derived. This element is derived for one-dimensional problems and extended for three-dimensional problems. The elasto/plastic formulation of the material stiffness is described. A brief example is presented, and the results are

This paper gives the results of earthquake response analysis of nuclear power plant buildings with reactor VVER 440 in accordance with the methodology of seismic margin assessment and generic implementation procedure. Earthquake resisting of all the important buildings was considered taking a dynamic linear and nonlinear effects on soil-structures interaction into account. Limits of seismic resisting of building are expressed by high confidence low
