“…Die gleichen Einheitstemperaturzeitkurven stützen die Sichtweisen der MBO und der Fachkommission Bautechnik der ARGEBAU hinsichtlich des Bestandsschutzes für die Feuerwiderstandsfähigkeit von Bauteilen in rechtmäßig errichteten Gebäuden. Ausführliche Erläuterungen zu der Thematik Bestandsschutz sind zu entnehmen.…”

“…Die Tab. enthält Anforderungen an statisch unbestimmt gelagerte, feuerbeständige Stahlbetondecken unter Berücksichtigung der Anordnung der Stützbewehrung aus den Fassungen der DIN 4102 seit 1934 bis heute (s. ). Der Tabelle ist zu entnehmen, dass statisch unbestimmt gelagerte, feuerbeständige Stahlbetondecken eine Mindestbauteildicke von 100 mm besitzen müssen (Einführung des Wärmedämm‐ oder Isolationskriteriums).…”

Special-purpose solutions in the fire-protective evaluation of construction details Very often components or construction details in existing buildings but also in new buildings cannot be evaluated with regard to its fire resistance ability considering established technical building regulations. There are no regulations for the evaluation of such components or construction details as these specific construction details have not been evaluated by a certified test authority. However, these components and construction details very often can be classified in fire resistance classes e. g. by evaluating fire tests, with regard to DIN 4102-4, on the basis of similar proof of usability or only by pragmatic considerations. Since introducing the technical approval of the fire protection Eurocodes more often engineering methods of fire protection are used based on these Eurocodes by using temperature assessment in order to secure the evaluation results. Within this essay we show methods and ways of fire-protective evaluation for components and construction details. The approach of proof including dimensions of possible upgrade measurements if necessary are being illustrated by examples of use out of practical experience. At the same time different materials such as steel, concrete and wood will be treated with different fireproof products. The essay is to explain ways of evaluation of components and construction details involving fire-proof requirements including upgrade measurements also especially for existing buildings.
