Using the Direct Determined Fully Probabilistic Method (DDFPM) for determination of failure

Popis výsledku v původním jazyce

Direct determined fully probabilistic method (DDFPM) has been developed as an alternative for Monte Carlo method in the assessment of structural reliability in probabilistic calculations. Input random quantities (such as the load, geometry, material properties or imperfections) are expressed as histograms in the calculations. In the common DDFPM calculations, all input random variables are combined with each other. The number of possible combinations is equal to the product of classes (intervals) of allinput variables. With rather many input random variables, the number of combination is very high. Only a small portion of possible combinations results, typically, in failure. When DDFPM is used, the calculation takes too much time, because combinationsare taken into account that does not contribute to the failure. Efforts to reduce the number of calculation operations have resulted into the development of algorithms that provide the numerical solution of the integral that defines form
