DESTRUCTION MECHANISMS IN CONCRETE MATERIAL

Models for fire loads and arrangements for testing are presented on the basis of the damage patterns which may be observed on a concrete component in the event of a fire. Prior definition of the protective goals is necessary for the correct dimensioning of the protective measures, which should extend beyond the structural aspects. In addition, the author presents a concrete concept which is largely resistant to the damaging mechanisms. Tests with the highest normative fire loads in Europe confirm the validity of the concept. These considerations are based on the example of tunnel construction, but they are similarly valid for applications and fire protection dimensioning in other types of concrete structures. (A)
