| The compilation of articels and documents presented on this website focuses on new methods for appropriately taking account of structural models and parameters with respect to their uncertainty. These models and parameters are usually established on the basis of plans, drawings, measurements, observations, experiences, expert knowledge, codes and standards, and so on. In general, certain information and precise values do not exist. Uncertainty may result, e.g., from human mistakes and errors in the manufacture, from the use and maintenance of constructions, from expert evaluations, and from a lack of information. Small samples, changing reproduction conditions, and imprecise results of measurements are usual starting points for defining structural models and parameters.These facts show that structural engineering is significantly characterized by uncertainty. In order to perform realistic structural analysis and proper safety assessment this uncertainty in both data and models must be appropriately taken into consideration. Herein, computational models that are capable of numerically simulating the system behavior of the chosen structural model are considered to be sufficiently accurate; their uncertainty, e.g., resulting from weak formulations or numerical impreciseness, is not subject of the consideration. |
