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.
