Anotace
The aim of the project is developed reliable, theoretically based simulation tools for time-dependent analysis of the failure probability of members of load bearing steel structures exposed to repeated loading. The phenomena of fatigue damage of steel elements will be examined using experiments and computer simulations. Analysis of existing computer models will be performed. New computer models and numerical methods for time dependent reliability analysis of steel structures will be developed and effectively implemented. In contrast to commonly used ad-hoc approaches to solving problems of the service life of existing structures, the uniqueness of the proposed project lies in the merging of all named aspects into an integrated framework.
