Abstract

Çalışmada, ultra yüksek performanslı beton (UYPB) plakalarla güçlendirilmiş eğilme dayanımı yetersiz betonarme kirişlerin davranışı deneysel olarak incelenmiştir. Güçlendirme amacıyla kullanılacak plakaların imalatı için %3 fiber hacmine sahip UYPB kullanılmıştır. Bir tanesi kontrol numunesi olmak üzere, kalınlık değişiminin eğilme davranışı üzerindeki etkilerini gözlemlemek amacıyla 3 farklı kalınlıkta UYPB plaka üretilmiş (30 mm, 50 mm ve 70 mm) ve plakalar betonarme kirişlere uygulanmıştır. Kirişler, dört noktalı eğilme yükleri altında test edilmiştir. UYPB plaka ile güçlendirilmiş numunelerde yük taşıma kapasitesinde %20 ila %58 arasında değişen oranlarda artış elde edilmiştir.

Investigate the Influence of Different UHPC Laminates Thickness to the Flexural Capacity

Abstract

The
aim of this study is to investigate behavior of reinforced concrete
beams with insufficient flexural strength which are reinforced by
ultra high performance concrete (UHPC) were examined experimentally.
UYPC with 3% fiber volume was used for manufacturing laminates which
will be used for reinforcing. UHPC having three different thickness
(30 mm, 50 mm and 70 mm) where one of them will be control sample was
used for observing effect of change in thickness over flexural
behavior were manufactured and applied over reinforced concrete
beams. RC Beams were tested under four -point bending loads. Increase
in load carrying capacity varying with 20%-58% rates were obtained in
samples which were reinforced with UHPC.
