| Description
| - The topic of the paper is the probabilistic analysis of the ultimate limit state of a steel strut loaded by permanent and long-time single variation action. The failure probability misalignment according to the EN1990 concept of a structure designed according to the EUROCODE 3 is analyzed here. In the stochastic model, material and geometrical characteristics of a hot-rolled steel cross-section are considered according to the experimental research results. The initial curvature shape and size variability of the beam axis is modelled, in detail, by applying the random fields. The functional dependence between the failure probability and the correlation length of a random field is analyzed here. The probabilistic analysis is completed by the fuzzy analysis of the influence of uncertainties on the failure probability. The fuzzification process of coefficients of model uncertainties and the deffuzification process of the fuzzy number of the output failure probability are described. The failure probability

- Článek prezentuje pravděpodobnostní analýzu mezního stavu únosnosti ocelové vzpěry zatížené stálým a dlouhodobým nahodilým zatížením. Je analyzována nevyrovnanost pravděpodobnosti poruchy dle konceptu EN1990 konstrukce navržené dle EUROCODE 3. Ve stochastickém modelu jsou materiálové a geometrické charakteristiky ocelového válcovaného průřezu uvažovány dle výsledků experimentálního výzkumu. Variabilita tvaru a velikosti počátečního zakřivení osy prutu je modelována velmi podrobně s užitím tzv. náhodných polí. Je analyzována funkční závislost mezi pravděpodobností poruchy a korelační délkou náhodného pole. Pravděpodobnostní analýza je doplněna fuzzy analýzou vlivu modelových neurčitostí na pravděpodobnost poruchy. Je popsán proces fuzzifikace součinitelů modelových neurčitostí a proces defuzifikace fuzzy čísla výstupní pravděpodobnosti poruchy. Fuzzy analýza pravděpodobnosti poruchy byla vyhodnocena podle obecného pri (cs)
