Strengthening of Columns with Different Innovative Composite Materials for RC Buildings without Sufficient Earthquake Resistance

Öz:
The Turkey includes the world's second most active faults and is geographically situated at a very high seismic activity. Research on strengthening RC (reinforced- concrete) structures without adequate earthquake resistance has become an extremely important issue. Taking into account the objectives of this research, an experimental study is designed to strengthen the columns without adequate earthquake resistance by using carbon-reinforced-fiber-fabric (CFRP) strips and textile-reinforced-mortar (TRM) layers with two separate types of advanced composite materials. The variables evaluated within the study horizon are the composite material type used for strengthening, the width of the strip, and whether or not the anchor is used at the point of strip overlap. In this experiment, nine RC column were produced and were tested by affecting axial load, which are the reference test specimens without strengthening and eight RC column test specimens strengthened with two separate types of composite material. The load-displacement behavior, initial stiffness value, energy dissipation capacities, ultimate load capacity and displacement ductility ratios have been measured according to the test results. It was also examined which of the two different composite materials used to strengthen the columns of the RC is more efficient in improving the columns performance.

Yeterli Deprem Dayanımı Olmayan Betonarme Binalar için Kolonların Farklı Yenilikçi Kompozit Malzemelerle Güçlendirilmesi

Öz:
Türkiye, dünyadaki en aktif ikinci fayları barındırmakta ve coğrafi olarak çok yüksek sismik aktiviteye sahip bir bölgededir. Yeterli depreme dayanımı olmayan betonarme yapıların güçlendirilmesi konusu son derece önemli bir araştırma konusu haline gelmiştir. Bu çalışma kapsamında, iki farklı tip yenilikçi kompozit malzeme olan karbon takviyeli elyaf kumaş (CFRP) şeritleri ve tekstil takviyeli harç (TRM) katmanlar ile yeterli deprem dayanımı olmayan betonarme kolonların güçlendirilmesi hedeflenmiştir. Çalışmada incelenen değişkenler, güçlendirme için kullanılan kompozit malzeme türü, şerit genişliği ve şerit örtüşme noktasında ankraj kullanılıp kullanılmadığıdır. Bu çalışmada, güçlendirme uygulanmayan referans test numunesi ve iki farklı tip kompozit malzeme ile güçlendirilmiş sekiz adet RC kolon olmak üzere toplam 9 kolon test numunesi üretilmiş ve eksenel yükleme etkisi altında test edilmiştir. Test sonuçlarına göre, yük-deplasman davranışı, nihai yük kapasitesi, ilk rijitlik değeri, deplasman süneklik oranları ve enerji emme kapasiteleri değerlendirilmiştir. Betonarme kolonların güçlendirilmesinde kullanılan iki farklı kompozit malzemeden hangisinin kolonların performansının iyileştirilmesinde daha etkili olduğu da incelenmiştir.
