Lifecycle Assessment of Structures and Probabilistic Performance Approaches

This contribution is particularly focused on the lifetime assessment of structures where the concept of risk informed decision is based on the structural performance. Regarding the lifetime performance of structures general aspects such as structural system, component-system performance assessment, the concept of robustness in the component-component-system interaction and its assessment framework are introduced. Furthermore, aspects of both deterministic and probabilistic performance evaluation approaches were investigated, while extra emphasis is given to the probabilistic performance assessment approaches. This illustration of the probabilistic performance approaches includes the concepts of uncertainty quantifications, hazard identification methods and techniques, and the formulation of random variables and stochastic structural deterioration processes. In addition, lifecycle performance assessment and prediction methods, approaches and tools for engineering structures are presented.
