The dramatic development of the computer technology allows to consider a transition from current structural reliability assessment methods developed in the pre-computer era, such as Partial Factors Method applied in Eurocodes, to probabilistic methods using simulation technique and the increasing potential of the available computers to its full. The paper briefly indicates the basics of a qualitatively new Simulation-Based Reliability Assessment Method, SBRA, applicable in the design and in codes. Hundreds of solved examples are available in the textbooks referred later in this paper (see also www.noise.cz/SBRA). Considering the application of SBRA, the paper turns attention to the substance of the reliability assessment of safety and serviceability of components and structures containing semi-rigid joints. Using pilot examples, the response of selected types of joints exposed to load combination is indicated, the reference values applied in the calculation of the probability of failure are defined and the analysis of the reliability function using simulation technique and leading to the calculation of the probability of failure Pf is indicated. The procedures and the results obtained according to the SBRA method and to the Eurocode EC3 are compared and discussed. Future studies on probabilistic reliability assessment of structure containing semi-rigid joints are indicated.
