The paper describes a somplex methodology for statistical, reliability and risk analyses of concrete bridges. It describes the virtual simulation used on the way from assessment of experimental result to reliability analysis. The whole approach is based on randomization of nonlinear fracture mechanics finite element analysis of concrete structures. Theoretical as well as practical application aspects are presented emphasizing the conceptual framework and key points of solution. Efficient techniques of both nonlinear numerical analysis of concrete structures and stochstic simulation method of Monte Carlo type have been combined in order to offer an advanced tool for assessment of realistic behavior of concrete structures from statistical and reliability point of views. Degradation aspects, as cartonation of concrete, corrosion of reinforcement, are included too, enabling reliability prediction in time. The next aim paper is to describe the software tools that came into existence for feliability assessment of bridges. It represents basically a combination of statistical simulation package FREET and nonlinear fracture mechanics software ATENA: Finally,the paper documents the most interesting application of this methodology and software tools for assessment of bridges from Austria and Italy.
