Anotace
This aim of the project is to develop reliable and experimentally supported simulation tools for time-dependent analysis of the failure probability of structural members made from highperformance concrete with an autogenous self-healing phenomenon, which are exposed to many times repeating loads. The autogenous self-healing phenomenon of high-performance concrete and its self-healing efficiency of damage induced by fatigue load will be analysed by experiments and computer simulations. Self-healing efficiency and its influence on the structural life-time extension will be inseparable part of this project. This will be studied by both general (whole geometry) and local (microstructure) material’s response. In contrast to commonly used ad-hoc methods for analysis of structural service lifetime the uniqueness of the proposed project lies in the combination of all named aspects into an integrated framework.
