Yapı taşıyıcı sisteminin önemli bir parçası olan betonarme kirişler ile ilgili bir çalışma yürütülmüştür. Bu çalışmalarda genellikle basit mesnet şartları dikkate alınmıştır. Ancak, betonarme binaların mesnet bölgelerinin ankastre mesnet şartlarına daha yakın olduğu bilinmektedir. Bu çalışmada, betonarme kirişlerde mesnet şartlarının değişimin kiriş kesme dayanımına etkisi araştırılmıştır. Bu amaçla, 4 adet tam ölçekli betonarme kiriş deney elemanı 4 noktalı eğilme sisteminde test edilmiştir. Bu deney elemanlarından iki tanesi basit mesnetli, iki tanesi ise ankastre mesnetli olarak test edilmiştir. Deney elemanlarının davranışlarının belirlenmesi için yük-deplasman eğrileri çizilmiş, rijitlik ve enerji tüketim kapasiteleri belirlenmiş ve deney sırasında çatlak oluşumları gözlemlenmiştir. Deney sonuçları incelendiğinde, ankastre mesnetli deney elemanlarının davranışlarının, aynı özellikteki basit mesnetli deney elemanlarının davranışlarından oldukça farklı olduğu görülmüştür.

INVESTIGATION OF SHEAR BEHAVIOR OF REINFORCED CONCRETE BEAMS UNDER SIMPLE AND FIXED SUPPORT CONDITIONS

Many experimental studies were carried out to research about reinforced concrete beams, which are an important part of the structural bearing system. In these studies, simple support conditions were generally taken into consideration. However, it is known that the support zones of beams in reinforced concrete buildings are closer to the fixed support conditions. In this study, the effect of the change of support conditions in reinforced concrete beams on the beam shear behavior was examined. For this purpose, 4 full-scale reinforced concrete beam elements were tested on a 4 point loading mechanism. Two of these specimens were tested with simple support and two with fixed support. In order to determine the behavior of the test elements, load-displacement curves were drawn, stiffness and energy consumption capacities were determined and cracks formed during the test were examined. When the test results were examined, it was found that the behavior of the fixed supported specimens was quite different from the ones of the simple supported specimens.
