Abstract

Various calculation methods based on the theory of probability and statistics are used for structural analysis and reliability assessment. Those methods so-called probabilistic have been becoming very popular recently. Using the probabilistic method, it is possible to analyse a safety margin defined in a computational model where at least some input characters are random. New method which are being developed now - Direct Optimized Probabilistic Calculation (“DOProC”) is a purely numerical method which uses no simulation or approximation techniques. Results of the probabilistic tasks are more accurate and, often, more fast to reach.
