Earthquake is an
unpredictable and inevitable fact, and the only effort to minimize the loss of
life and property is to design and build the structure to resist the forces
associated with earthquakes. Considering the Kobi, Northridge and Düzce
earthquakes in particular, it is foreseen that public buildings such as
hospitals, schools and multi-storey buildings should be protected with basic
isolators against earthquakes. Various attempts have been made to achieve an
earthquake-resistant design desired for buildings. As a result of these
initiatives, significant progress has been made, which is significantly
beneficial to reduce structural responses during an earthquake. The seismic
response control of base insulated structures must be examined using single-set
mass damper (STMD), multiple-set mass dampers (MTMDs) and distributed
multiple-set mass dampers (d-MTMDs) under different earthquake ground motions.
In this study, the structure was isolated with stratified rubber supports
(LRB), lead-core rubber bearings (NZ), friction pendulum system (FPS) and
flexible friction base insulator (R-FBI) isolation systems and on the top floor
STMD, MTMDs and MTMDs at floors and d-MTMDs on floors. Also, for the parametric
study, the insulator time period has been realized by changing between 2 and
2.5 and 3 sec. The mass ratio for all STMD cases was accepted as 2, 3, 5 and
10%. In addition, MTMDs were placed along the top floor as well as on the base
and distributed throughout the height of the isolated structure.

Deprem öngörülemez ve
önlenemez bir gerçektir, can ve mal kaybını en aza indirgemek için tek çaba,
yapıyı depreme bağlı kuvvetlere karşı koyacak şekilde tasarlanması ve inşa
edilmesidir. Özellikle Kobi, Northridge ve Düzce depremleri gözönünde
bulundurulduğunda hastane, okul gibi kamu binalarının ve çok-katlı binaların
depreme karşı temel izolatörlerle korunması gerekliliği öngörülmektedir.
Yapılar için istenen depreme dayanıklı bir tasarıma ulaşmak için çeşitli
girişimlerde bulunulmuştur. Bu girişimler sonucunda, bir deprem sırasında
yapısal tepkileri azaltmak için önemli ölçüde faydalı olan önemli ilerlemeler
kaydedilmiştir. Farklı deprem yer hareketleri altında tek ayarlı kütle
sönümleyici (STMD), çoklu ayarlı kütle sönümleyicileri (MTMD’ler) ve dağıtılmış
çoklu ayarlı kütle sönümleyicileri (d-MTMD’ler) kullanılarak, taban izolasyonlu
yapıların sismik tepki kontrolünün incelenmesi gerekmektedir.  Bu çalışmada yapı, tabakalı kauçuk mesnetler
(LRB), kurşun çekirdekli kauçuk mesnetler (N-Z), sürtünmeli sarkaç sistemi
(FPS) ve esnek sürtünmeli taban izolatörü (R-FBI) izolasyon sistemleri ile
izole edilmiş ve en üst katta STMD, MTMD’ler ve tabanda MTMD’ler ve katlarda
d-MTMD’ler ile donatılmıştır. Ayrıca parametrik çalışma için izolatör zaman
periyodu 2 ile 2,5 ve 3 sn arasında değiştirilerek gerçekleştirilmiştir. Tüm
STMD durumları için kütle oranı %2, 3, 5 ve %10 olarak kabul edilmiştir. Buna
ek olarak, MTMD’ler en üst katın yanı sıra taban üzerine yerleştirilmiş ve
izole edilmiş yapının yüksekliği boyunca dağıtılmıştır.
