Türkiye’de mevcut az veya orta katlı betonarme binaların birçoğu düşük performanslı beton kullanımı, yapım ve tasarım hataları nedeniyle deprem yükleri altında düşük yapısal performans göstermektedir. Betonarme binalarda donatı korozyonu taşıyıcı elemanları ve yapısal sistemin bütününü olumsuz etkiler. Bu çalışmada aderans kaybı, beton ve donatı özelliklerinde değişime neden olan donatı korozyonuna maruz bir binanın yapısal performans değişimi ele alınmaktadır. Bu amaçla zemin katında farklı korozyon senaryoları uygulanan 5 katlı tipik bir betonarme bina tasarlanmıştır. Binanın her bir korozyon senaryosu altında EC-8’e göre yapısal performansı değerlendirilmiştir. Statik itme analizinde Seismostruct 2016 yazılımı kullanılmıştır. Elde edilen sonuçlar, uzun süreli etkiyen ileri seviyede seyreden donatı korozyonunun yapısal performansı olumsuz etkilediğini göstermektedir. Binanın korozyonsuz durumuna kıyasla, performans seviyelerinde ve hedef deplasmanlarında kayda değer değişimler gözlenmiştir.

Many of the low or medium-story reinforced concrete buildings existing in Turkey have poor structural performance under earthquake loads due to use of low performance concrete, design and construction errors. Rebar corrosion adversely affects structural performance of all structural members and the entire structural system in reinforced concrete buildings. This paper presents structural performance changes on a selected building affected rebar corrosion that cause important changes in concrete, reinforcement steel properties and bond loss. A typical five-story reinforced concrete building is designed to apply different rebar corrosion scenarios at ground floor. Structural performance evaluation of the building with different corrosion scenarios are performed according to EC-8. The software Seismostruct 2016 is used for pushover analysis. The results show that structural performance of the building is negatively affected from high level and long term rebar corrosion aspect. Significant changes in performance levels and in target displacements of the building are observed as compared with the results of the uncorroded state of the building.
