Description
  • V článku je analyzován vliv náhodných a fuzzy nejistot o imperfekcích na náhodnou a fuzzy neurčitost výpočtu únosnosti ocelového rovinného rámu. Byly zmíněny nejdůležitější problémy a souvislosti, s nimiž se projektant může setkat při návrhu nosných soustav spolehlivostním výpočtem. S cílem postupného začlenění pravděpodobnostního posudku do výrobní praxe bude diskutována zejména uplatnitelnost těch metod, které mají univerzální charakter. Tuto podmínku splňuje metoda konečných prvků v kombinaci se simulačními metodami typu Monte Carlo, u nichž nejsou omezeny počty náhodných veličin a lze u nich relativně snadno zavádět i složité statistické závislosti. Obecně bude zmíněn přínos pravděpodobnostního posudku v porovnání s posudkem nosné soustavy podle Eurocodu, např. pro stanovení a upřesnění spolehlivosti existujících nosných soustav. V této souvislosti bude diskutována problematika referečních hodnot v podmínkách (cs)
  • The analysis of the influence of stochastic and fuzzy uncertainties of imperfections on the stochastic and fuzzy uncertainties of the load-carrying capacity of a steel plane frame is presented. On a simple example of a steel plane frame, the analyses of the possibilities of system imperfections implementation as random variables are performed. The influence of uncertainty of random characteristics of the correlation coefficient between the random initial inclinations of the frame columns on the load-carrying capacity of the frame is studied. In the next stage, the system imperfections are considered as fuzzy numbers. The fuzzy load-carrying capacity was determined as a fuzzy number, utilizing the general extension principle. The comparison of fuzzy and stochastic load-carrying capacity with the design standard load-carrying capacity acc. to EUROCODE 3 is performed in the final stage.
