Abstract



The estimation of the
seismic performance of reinforced concrete structures exposed to corrosion is
more difficult than uncorroded structures. By this experimental study, it was
aimed to keep light on the studies to be done on the reinforced concrete members
exposed to corrosion. Five full-scale reinforced concrete columns were
corroded for different corrosion levels by using the accelerated corrosion
method. The corroded reinforced concrete columns were subjected to monotonic
loading under constant axial load and, their yield and ultimate loads,
ductility ratios and energy absorption capacities were obtained by
experimentally. The actual corrosion levels in the reinforced concrete
columns were obtained by breaking the reinforced concrete columns after the loading
tests and extracting all embedded reinforced concrete bars from the concrete.
As a result of this experimental study, the weaknesses of monotonic loading
compared to reversed-cyclic loading were evaluated for considered earthquake
indicators. Based on the obtained experimental test results, important
recommendations were suggested for further corrosion studies. Within the
scope of this study, the ductility ratios and energy dissipation capacities
of corroded reinforced concrete columns were decreased as the corrosion
levels were increased under the influence of monotonic loading. The
confinement effect up to a certain value of corrosion levels and regarding
with increasing in earthquake indicator could not been clearly observed under
the influence of monotonic loading. Two empirical models to predict the
ductility ratios and energy dissipation capacities were developed to be used
for seismic assessment of corroded reinforced concrete columns considering
the unilateral failure mode.

Abstract



Korozyona maruz kalmış betonarme yapıların sismik
performanslarının tahmin edilmesi korozyona uğramamış yapılara göre daha
zordur. Gerçekleştirilen bu deneysel çalışma ile birlikte korozyona maruz
kalmış betonarme elemanları üzerine yapılacak olan çalışmalara ışık tutulması
amaçlanmıştır. Beş adet tam ölçekli betonarme kolonu hızlandırılmış korozyon
yöntemi kullanılarak farklı korozyon oranları için paslandırılmıştır.
Paslandırılmış betonarme kolonları sabit eksenel yük altında monotonik
yüklemeye tabi tutularak, akma ve nihai yükleri, süneklik oranları ve enerji
yutma kapasiteleri deneysel olarak elde edilmiştir. Betonarme kolonlarındaki
gerçek korozyon oranları yükleme deneylerinden sonra betonarme kolonlarının
kırılarak ve gömülü olan tüm betonarme donatılarının çıkartılması ile elde
edilmiştir. Yapılan deneysel çalışma sonucunda, monotonik yüklemenin tersinir-tekrarlanır yüklemeye
göre zayıf yönleri göz önüne alınan deprem indeksleri açısından
değerlendirilmiştir. Elde edilen deneysel sonuçlar doğrultusunda ileriki
korozyon çalışmaları için önemli önerilerde bulunulmuştur. Gerçekleştirilen
bu çalışma kapsamında, paslanmış betonarme kolonlarının monotonik yükleme
etkisi altında süneklik oranları ve enerji yutma kapasiteleri artan korozyon
oranına bağlı olarak azalmıştır. Monotonik yükleme etkisi altında pasın
belirli oranlarına kadar sağlamış olduğu sargı etkisi ve buna bağlı olarak
deprem indekslerindeki artışlar net bir şekilde görülememiştir. Tek
doğrultuda göçme modu kabulü ile yapılacak olan sismik değerlendirmelerde
kullanılmak üzere paslanmış betonarme kolonların süneklik ve enerji yutma
kapasitelerinin tahmin edilebilmesi için iki ampirik model
geliştirilmiştir.
