|The project focuses on improvement of computational techniques for assessment of the residual life of cement-based composites under long-term cyclic loading, particularly considering the following factors: material composition, fracture properties, frequency of loading, and varying load amplitude. Non-linear numerical models based on cumulative internal damage of the material and utilizing Wöhler (S–N) curves will be developed. Input data for 2D and 3D FE models will be obtained from tests on selected cement-based composites with static and fatigue loading (basic database for normal concrete as well as for two classes of high performance concrete will be created). FEM calculations will be used for investigation of limit values for initiation of fatigue damage and fatigue crack growth. The results will be applied in durability assessment of civil engineering structures subjected to cyclic loading such as transport structures and their components, high-rise buildings, etc.
