Description
Summary:Advances in computer technology and simulation techniques allow for considering a transition from semiprobabilistic structural reliability assessment concepts, such as partial factor design (PFD), to a fully probabilistic concept applicable in design practice. Referring to the proposed Simulation-Based Reliability Assessment concept (SBRA), reengineering of the reliability assessment process is discussed. The SBRA concept corresponds to the limit states philosophy. The input variables are expressed by bounded histograms, the loads are represented by load duration curves and the Monte Carlo method-based computer programs nad modern PC are used for analyzing the reliability functions containing random variables. The reliability (that is, safety, durability and serviceability) is expressed by probability of failure P f. Using selected examples and a parametric study, the potential, efficiency and advantages of the proposed method applicable in design practice are illustrated.
