Aim: The concept of structural reliability is not used here solely as a concept that concerns physical structural collapse, but also as a reliability with respect to other types of functional failure.
The aim of the course is to give the participants a general appreciation of the design problem as a decision problem under uncertain conditions. Moreover, the goal is to make the participants able to apply probabilistic methods for reliability evaluation in connection with the analysis or the design of structures.

Contents: Motivation for reliability problem, the model problem, uncertainty sources. Traditional methods, safety factors, codes, accepted reliability level. Probabilistic information. The simple reliability index, the geometric reliability index, the generalized reliability index. Transformation. Sensitivity analysis. Monte Carlo methods. Load combinations. Statistical uncertainty and model uncertainty. Decision philosophy. Reliability of existing structures. Systems reliability. The necessary probabilistic concepts and tools are introduced (repeated) briefly where they are needed. The computer program MATLAB is used as the basis for problemsolving.
