Abstract (2. Language): 
It is known that, especially in Turkey, many existing reinforced concrete buildings constructed in pre 1998 era, have many structural faults, due to deficiencies both in seismic code of the time and in application process. The column-beam regions are subjected to the high shear stresses under the seismic forces. And thus causing sudden failures since the required mode of failure is not accomplished. In this research, seismic behavior of beam column joint which is designed according to the old seismic code of Turkey is investigated experimentally, and then the damaged specimen is repaired by chemical epoxy and re-tested. As a conclusion, significant improvement is obtained in lateral load-drift behavior, stiffness degradation and energy dissipation capacities of repaired specimen.
Abstract (Original Language): 
Özellikle Türkiye’de, 1998 öncesi yapılmış betonarme binalarda, gerek yönetmelik eksiliğinden, gerekse uygulama hatalarından dolayı çeşitli yapısal problemlerin mevcut olduğu bilinmektedir. Kolon kiriş birleşim bölgeleri deprem kuvvetleri altında yüksek kayma gerilmelerine maruz kalmaktadır. Bu da arzu edilen göçme senaryosu gerçekleşemeden binaların daha evvelden kolon-kiriş birleşim bölgelerinden ani göçmelere neden olmaktadır. Bu çalışmada eski yönetmeliklere uygun yapılmış, kolon kiriş birleşim numunelerinin sismik davranışı deneysel olarak incelenmiş ve sonra hasarlı numune kimyasal harçlar ile onarılarak tekrar teste tabii tutulmuştur. Sonuç olarak, tamir edilen numunenin Yatay yük –ötelenme davranışı, rijitlik kayıpları ve Enerji Tüketim kapasitesinde önemli derecede bir artış olduğu elde edilmiştir.
