Ayarlı kütle sönümleyicilerinde yerleşim ve parametre değişiminin yapısal sistem performansına etkisi

Öz

Bu çalışmada, Ayarlı Kütle Sönümleyicilerinin (AKS) yapısal sistem üzerinde etkileri parametre değişimi ve farklı katlara yerleşimleri dikkate alınarak incelenmiştir. Çok serbestlik dereceli çelik konstrüksiyon bir bina modelinin için tasarlanan AKS, bu bina modelinin her bir katına ayrı ayrı eklenerek sistem cevapları incelenmiştir. Her bir kat için ayrı bir simülasyon yapılmıştır. Ayrıca, kat yerleşimlerinin yanında değişiminin etkilerini incelemek amacıyla, AKS’nin farklı kütle, rijitlik ve sönüm parametreleri kullanılmıştır. Sistem cevapları farklı depremler etkisinde analiz edilmiştir. AKS parametrelerinin belirlenmesinde farklı yaklaşımlardan faydalanılmıştır. Sonuçlar, AKS’nin yerleşimi ile parametre değişimlerinin sistem performansını etkilediği, ve üst katlara doğru AKS yerleşimi ile yüksek kütle oranlarının, sistem cevaplarını daha etkili bir şekilde bastırdığını göstermiştir.

The Effect of Location and Parameter exchange of set mass damping on the structural system performance

Öz

This study investigates the effects of Tuned Mass Dampers (TMDs) on the structural system by considering parameter variation and placement. A multi-degree-of-freedom steel construction building model is designed by considering the parameters of the building model, and the system responses are investigated by adding the TMD to each floor of this building model separately. A separate simulation was performed for each floor. In addition, different values of the TMD's mass, stiffness, and damping parameters were used to investigate the effects of different parameters besides the story placements. Different approaches were utilized to determine the TMD parameters. The results show that the parameter variations with the placement of the TMD affect the system performance. The parameters obtained at higher mass ratios in the parameter ranges determined by the placement of the TMD towards the upper floors suppress the system responses more effectively.
