Probabilisticmethodsallowtotakeintoaccounttherandomnessanduncertaintyinthedesignandreliabilityassessment of building structures (). In the past, a number of probabilistic methods have been developed, which were used in solution of many engineering tasks. The problem is often the inaccuracy of the resulting probability of failure and also the high machine time of the calculation. The solution can be the parallelization, which can allow to obtain the result in a fragment of the original processing time while preserving the accuracy of the solution. The article focuses on the parallelization by the newly developed Direct Optimized Probabilistic Calculation–”DOProC”method,whichwasusedtosolveanumberofengineeringtasks,eginthe field of fatigue-stressed structures.
