Summary
This subject is focused on the stochastic mechanics and the probabilistic approach of reliability assessment, which use simulation techniques of direct Monte Carlo (MC) method. Analytical models, numerical models (FEM) and fully probabilistic Simulation-Based Reliability Assessment (SBRA) Method are applied. Software Anthill, Mathcad, MSC.Marc/Mentat and ANSYS are used in practical applications.
In the introduction are explained the basic conceptions of the theory of probability, statistics, reliability, MC method, SBRA method and its new development tendencies "Integrated – fully probabilistic Design" (ID). Into ID, which can exert a direct influence of economy, ecology, politics etc., belongs Performance-Based Design (PBD), Life-Cycle Assessment (LCA), Risk Engineering (RE) etc.
