"Fire remains one of the most serious potential risks to buildings and underground structures. Extensive use of concrete elements as structural materials has led to the need to fully understand the effects of fire on both concrete and its reinforcement. \u00A0The recent fatal fires particularly in tunnels have emphasized the indispensability to solve the problem from the standpoint of safety and find new methods for clarification of this phenomenon. For this purpose it is inevitable to take into consideration very many variables arising in description of the aftermath of fire loading. Formerly EU countries issued couple of recommendations on loading concrete during experiments. From the experiments respecting the recommendations theoretical contemplations are to be formulated, numerical processes to be proposed and good chance to feed computational procedures by proper data respecting test observations will be increased. It appears that very considerable fact is the choice of fiber material, fiber mixture and the material of the concrete matrix. Those will be one of the most essential goals of the investigation envisaged."@en . .
