Özet:

 In this paper, a numerical study was carried out on the effectiveness of the active earthquake control method in improving the earthquake response of RC buildings. High damping rubber bearing design was made according to the criteria of the Uniform Building Code. Three different types of isolators were obtained geometrically. Passive earthquake control of the building was provided by placing these isolators under the columns. For active earthquake control of the building, controller design was realized by integrating it into the FE transient analysis in ANSYS. The active earthquake control design was studied using a force-based and displacement-based controller with acceleration and displacement feedback. The linear dynamic earthquake analysis in the time history of all three states of the building un-controlled, passive, and active-controlled was made using the acceleration record of the Seferihisar İzmir earthquake. When the results are examined, it is seen that the active earthquake control method provides almost all of the positive behavior expected from the passive earthquake control method. In addition, it eliminates some of the disadvantages of the passive earthquake control method.

 Bu makalede, betonarme binaların deprem davranışını iyileştirmede pasif deprem kontrol yöntemine bir alternatif olarak aktif deprem kontrol yönteminin etkinliği üzerine sayısal bir çalışma gerçekleştirilmiştir. Binanın pasif kontrolü için gerekli olan yüksek sönümlü kauçuk izolatörlerin tasarımı Uniform Bina Yönetmeliği kriterlerine göre yapılmıştır. Geometrik olarak üç farklı tip izolatör elde edilmiştir. Bu izolatörler kolonların altına yerleştirilerek binanın pasif deprem kontrolü sağlanmıştır. Binanın aktif kontrolü için kullanılan kontrolör tasarımı, ANSYSte sonlu eleman tabanlı zaman tanım alanında analizlere entegre edilerek gerçekleştirilmiştir. Aktif deprem kontrol tasarımı, ivme ve yer değiştirme geri beslemeli kuvvet tabanlı ve yer değiştirme tabanlı bir kontrolör kullanılarak incelenmiştir. Yapının her üç durumunun kontrolsüz, pasif kontrollü ve aktif kontrollü zaman tanım alanında doğrusal deprem analizi, Seferihisar İzmir depreminin ivme kaydı kullanılarak yapılmıştır. Sonuçlar incelendiğinde aktif deprem kontrol yönteminin pasif deprem kontrol yönteminden beklenen olumlu davranışların tamamına yakınını sağladığı ve bununla birlikte pasif deprem kontrol yönteminin bazı dezavantajlarını da ortadan kaldırdığı görülmektedir.
