Description	Hlavním cílem výzkumu bude zaměřen na popis změn materiálových vlastností vláknobetonů tunelové obezdívky, které jsou vystaveny vysokým teplotám. Vychází se z velkého rozsahu testů v Rakousku a v tomto projektu se připraví teoretický a numerický model. Vhodným se jeví metoda SPH (Blobs method). (cs) Elevated temperature, to which concrete in tunnel linings is sometimes exposed, is very dangerous phenomenon for material deterioration and, consequently, for possible failure of such structures. Increase of temperature above 200°C reduces very dramatically the compressive strength of concretes based on Portland pasta. The tensile strength at bending behaves similarly. At high temperatures chemical decomposition of calcium-silicate-hydrate occurs, which is the main bearer of mechanical property of the concrete. The study will start with large extent of experiments conducted in TU Innsbruck, in which the investigator took part during her doctoral study. The main substance of the project is to formulate and numerically work out those results. For the purpose of the project it appears to be promising to apply a new numerical method SHM (smooth partical method), which will be developed in details including convergence studies. (en)
