Rheological research works investigate for fire case the material behavior of small specimens and derive from the test results material laws to determine the behavior of structural elements due to fire exposure. However, as it is known, the heat and mass transport processes can significantly happen in different phases in macro concrete elements. Besides, in case of a fire, different heating rates occur in the cross section of structural elements. The validity of the transferred test results from small test specimens to the material behavior of structural elements indicates a phenomenon, which has not been investigated up to now. Such a research work has been done for the first time through close cooperation of subprojects A and B3 of SFB (Sonder-ForschungsBereich: A special fire research activity for structural elements in Braunschweig Technical University, 1971-1986). The results of the rheological investigations presented in this paper can lead to a new research conception about the determination of realistic fire behavior of concrete structures. By means of further purposive research work, it will be possible to reproduce the structural behavior in case of fire with simple but realistic mathematic-rheological relationships.

Reolojik araştırma çalışmaları, yangın durumunda, malzeme davranışını belirlemek için küçük boyutlu numuneler kullanmakta ve deney sonuçlarından yapı elemanlarının yangın davranışını belirlemede kullanılacak malzeme davranış kanunlarını saptamaktadır. Bununla beraber, bilindiği üzere, beton makro elemanlarda ısı ve kütle taşınımları önemli ölçüde farklı fazlarda meydana gelmektedir. Küçük numunelerden elde edilmiş olan deney sonuçlarının, yapı elemanlarına tatbikinin geçerliliği, şimdiye kadar araştırılmamış bir fenomen teşkil etmektedir. Böyle bir araştırma çalışması ilk defa SFB ye ait (Özel Araştırma Alanı : Braunschweig Teknik Üniversitesi’nde yapı elemanlarının yangın davranışı üzerine özel araştırma aktivitesi) A ve B3 alt araştırma projelerinin yakın çalışması sonucunda gerçekleştirilmiştir. Bu çalışmada ortaya konan reolojik araştırma sonuçları, beton yapı elemanlarının gerçekçi yangın durumunu belirlemede yeni bir araştırma kavramına öncelik edebilir. İleride amaca yönelik araştırma çalışmalarında yangın durumunda yapı elemanlarının gerçek davranışını, basit matematik-reolojik bağıntılarla belirlemek mümkün olacaktır.
