Abstract: | It is common concern for structural engineer to design building that can withstand high
seismic activity in order to maintain both lives and building integrity. For this purpose,
energy dissipating devices are invented in order to absorb the energy delivered to the
building. The seismic behavior of steel structural building equipped with two types of
energy dissipating devices including both viscos and friction dampers for 5, 10, and
20 story steel buildings is investigated in this study. The performance is assessed by
means of story drift, base shear, roof displacement, structure ductility, yield strength,
energy and building performance. These parameters are evaluated through nonlinear
pushover and time history analysis conducted using ETABS2017 in accordance with
TBDY2018. Results indicate that viscous damper placed at the outer corner of the
structure yielded the best performance among the other locations and damping devices
where it reduced the base shear by 69% and 64% in average for both directions X and
Y respectively compared to the results of moment resisting frames. Also, the roof
displacement reduced by 85% and 81% in average for both directions X and Y
respectively compared to the results of moment resisting frames. ÖZ:
Yüksek sismik riske sahip bölgelerde can güvenliği ve yapı bütünlüğünü koruyacak
bir tasarım yapmak inşaat mühendislerinin ortak arzusudur. Bu amaçla, deprem
esnasındaki enerjinin bir kısmını azaltmak için günümüzde birtakım araçlar
geliştirilmiştir. Bu çalışmada, 5, 10 ve 20 katlı viskoz ve sürtünme sönümleyicili çelik
binaların sismik davranışı incelenmiştir. Yapılan analizlerde kat ötelemeleri, taban
kesme kuvvetleri, yapı sünekliği, akma dayanımı, çatı deplasmanları, enerji ve bina
performansları incelenmiştir. Bu parametreler TBDY2018 uyarınca, ETABS2017
programı kullanılarak yapılan doğrusal olmayan pushover ve zaman tanım alanında
analiz yöntemleriyle değerlendirilmiştir. Sonuçlar, yapının dış köşesine yerleştirilmiş
viskoz sönümleyicinin, diğer konumlar arasında en iyi performansı sağladığını ve
sönümleme cihazlarının moment dirençli çerçevelere kıyasla taban kesme kuvvetlerini
x ve y yönlerinde sırasıyla % 69 ve % 64 oranında azalttığı gözlenmiştir. Ayrıca, çatı
deplasmanları, moment dirençli çerçevelerin sonuçlarına kıyasla X ve Y yönlerinde
sırasıyla% 85 ve% 81 oranlarında azalmıştır. |
