Abstract

Traditionally built tall buildings may be inadequate to absorb the energy released during major earthquakes. Connecting two neighboring tall buildings with fluid viscous damping (FVD) devices could be an effective method of absorbing energy. In this study, two adjacent tall buildings on three different soil types are connected with viscous damping devices under ground motion. After that; the values of displacement, acceleration, and shear force obtained from fixed support case (no soil) are compared with the values obtained from three different soil types. Six different connection models are defined by changing location and number of the fluid viscous dampers. Soil model is created by using viscous boundary conditions. In the modeling and analysis, ANSYS R19.2 computer program was used. According to the results, fluid viscous dampers are very effective on the dynamic response of the buildings exceeding more than 40%. Soil types are also effective on the response. Besides, it is concluded that the most suitable connection type among the determined connection models is that the viscous damping device is connected to the top floor of the short building.

Sıvı Viskoz Sönümleyicilerle Birbirine Bağlanmış Komşu Yüksek Binaların Dinamik Davranışının Zemin-Yapı Etkileşimini Dikkate Alarak İncelenmesi

Abstract

Öz
Geleneksel olarak inşa edilen yüksek binalar büyük depremler sırasında çıkan enerjiyi sönümlemede yetersiz kalabilir. Komşu iki yüksek binanın birbirine sıvı viskoz sönümleme cihazları ile bağlanması enerjiyi sönümlemede etkili bir yöntem olabilir. Bu çalışmada deprem etkisi altında ve üç farklı zemin türü üzerindeki iki yüksek bina birbirine viskoz sönümleyici cihazlar ile bağlanmıştır. Sonrasında ankastre mesnet üzerinde elde edilen yer değiştirme, ivme, tepe ve taban kesme kuvvetleri değerleri üç farklı zemin türünde meydana gelen değerler ile karşılaştırılmıştır. Sıvı viskoz sönümleyicilerin yerleri ve sayısı değiştirilerek altı farklı bağlantı modeli belirlenmiştir. Viskoz sınır şartı kullanılarak zemin modeli oluışturulmuştur. Modellemeler ve analizler ANSYS R19.2 programıyla iki boyutlu olarak gerçekleştirilmiştir. Sonuçlar incelendiğinde sıvı viskoz sönümleyici cihazlar yapının dinamik davranışında %40’ı aşan iyileşmeler meydana getirmiştir. Ayrıca zemin türleri de sonuçlar üzerinde oldukça etkilidir. Bunun yanında belirlenen bağlantı modelleri arasında en uygun bağlantı şeklinin kısa binanın en üst katına viskoz sönümleyici cihazın bağlanması olduğu sonucuna varılmıştır.
