Abstract: | Dampers are the energy dissipating devices which resist lateral loads and displacement
in reinforced concrete structures. Viscous and Friction dampers dissipate partially the
earthquake energy into heat which is transferred in return into the atmosphere. In order
to check the effectiveness of viscous and friction damper in reducing earthquakes
effects, time history and pushover analysis are conducted into reinforced concrete
buildings of different stories levels (five, ten and twenty stories) with and without both
type of dampers. In addition, the performance of viscous damper is compared to that
of friction damper to find the variation between both types of dampers in dissipating
earthquake energy. This comparison is performed by implementing friction dampers
in the same places which viscous damper are implemented on and by achieving same
analysis methods done for structural buildings with and without viscous dampers.
Furthermore, for finding the optimum location of dampers in external structural frame,
viscous and friction dampers are placed in three different locations in outer frames for
each story level during time history and pushover analysis.
In other words, this study deals with studying the effectiveness of viscous and friction
damper, comparing the performance of both types of dampers and finding the optimum
locations of VD and FD in external frames. Viscous damper had the priority over
Friction damper in improving the seismic response of structural building and the
optimum location of dampers was the middle position of the outer frame. ÖZ:
Sönümleyiciler betonarme binalardaki deprem yüklerini ve yer değiştirmeleri
azaltmaktadır. Viskoz ve sürtünme sönümleyicileri deprem enerjisini kısmen sonunda
atmosfere aktarılan ısıya dönüştürür. Bu çalışmada, viskoz ve sürtünme
sönümleyicilerinin farklı kat yüksekliklerindeki ( beş, on ve yirmi kat) betonarme
binalardaki deprem etkilerini azaltmadaki etkinliğini kontrol etmek için zaman tanım
alanında ve statik itme hesap yöntemleri kullanılmıştır. Viskoz ve sürtünme
sönümleyiciye sahip çerçevelerle, sönümleyicisiz sistemler bu bağlamda
karşılaştırılmıştır. Ayrıca, en ideal yeri bulmak için dış yapısal çerçevelerdeki
sönümleyiciler üç farklı yere yerleştirilmiştir.
Başka bir deyişle, bu çalışma viskoz ve sürtünme sönümleyicilerinin etkinliğini
incelemek, her iki tip sönümleyicinin performansını karşılaştırmak ve dış çerçevelerde
viskoz ve sürtünme sönümleyicilerinin ideal yerlerini bulmakla ilgilidir. Viskoz
sönümleyici, yapısal binanın sismik performansını iyileştirmede sürtünme
sönümleyiciye göre daha etkilidir ve en ideal sönümleyici konumu dış çerçevenin orta
pozisyonu olarak bulunmuştur. |
