Sismik yalıtım sistemleri; köprü ayakları, havaalanları, hastaneler gibi yapılarda ve çok sayıdaki diğer yapılarda, tehlikeli depremlerin yıkıcı etkilerini önlemek veya azaltmak için ülkemizde birçok önemli yapıda kullanılmıştır. Çok soğuk kışlara veya günlük sıcaklık değişikliklerinin fazla olduğu yerlerde inşa edilen yapılarda bulunan kauçuk esaslı sismik yalıtıcıların davranışları zorlu çevre koşullarına göre değişebilmektedir. Düşük sıcaklıklarda kauçuğun sertleştiği ve yapılara aktarılan yükü arttıran yüksek rijitliğe neden olduğu çeşitli kereler analitik ve deneysel olarak gözlenmiştir. Bu nedenle onların farklı yük ve sıcaklık altındaki davranışlarının deneysel olarak da iyi anlaşılmasında fayda vardır. Bu araştırma son yapılan deneysel çalışmanın (bilyeli kauçuk mesnet adıyla anılan yeni geliştirilen sismik yalıtıcı) bir tamamlayıcısıdır. Yeni geliştirilen bilyeli kauçuk mesnetlerin üretilme kolaylığına ek olarak maliyet ve enerji dağıtma kapasiteleri gibi avantajlı tarafları vardır. Ancak onların düşük sıcaklıklardaki ve düşük hızlardaki davranışları henüz detaylı bir şekilde araştırılmamıştır. Farklı sıcaklık değerlerinde eksenel yük, basınç yükü ve yanal yer değiştirmeye maruz kalan bilyeli kauçuk mesnetlerin davranışı incelenmiştir. Bu çalışma sonucunda bilyeli kauçuk mesnetlerin soğuk iklim şartlarında ve sünmeden dolayı oluşabilecek olası ağır yer değiştirme davranışı hakkında bilgi verilmiştir.

Experimental evaluation of “ball rubber bearings” at different temperatures
Erdal, Serkan; Caner, Alp; Department of Civil Engineering (2010)
Rubber material used in seismic isolation systems has a tendency to stiffen in cold climate conditions. Structural responses of rubber based seismic isolation bearings are known to be temperature dependent. The main focus of this research is to investigate the temperature related behavior shifts at a certain type of a rubber based seismic isolation system. This research is a complementary study to a recent experimental study on a newly developed seismic isolator called “Ball Rubber Bearing” (BRB). BRBs can ...
Reliability and quantity based evaluation of structural proportions of several highway precast prestressed I girderbridges designed in an earthquake region
Toker, İldem; Caner, Alp; Department of Civil Engineering (2019)
Bridges located in earthquake regions are generally designed with using force or displacement methods specified in American and European Codes which are AASHTO and Eurocode basically. Current vision for design purposes proposes that reliability analysis requirements determine the loads, load factors and load combinations by means of statistical approach. The significant uncertainty about earthquake load resulted in use of different design approaches per different specifications. Different design methods and...
Broadband ground motion simulation within Duzce city (Turkey)
Özmen, Ekin; Askan Gündoğan, Ayşegül; Kestel, Sevtap Ayşe; Department of Earthquake Studies (2019)
Earthquakes have more hazardous and devastating effects in populated areas. To prevent damage and reduce the risks, broadband records are collected to use in the seismic hazard assessment and engineering seismology. In areas with significant seismic activity and insufficient seismic networks, the simulated ground motions become more important. Broadband ground motion simulations are performed for 12 November 1999 Duzce earthquake. Deterministic simulations are performed for low frequency part and stochastic...
Energy based seismic performance assessment of reinforced concrete columns
Acun, Bora; Sucuoğlu, Haluk; Department of Civil Engineering (2010)
Severe seismic events in urban regions during the last two decades revealed that the structures constructed before the development of modern seismic codes are the most vulnerable to earthquakes. Sub-standard reinforced concrete buildings constitute an important part of this highly vulnerable urban building stock. There is urgent need for the development and improvement of methods for seismic performance assessment of existing reinforced concrete structures. As an alternative to current conventional force-ba...
Nonlinear analysis of RC frames retrofitted with structural steel elements
Akpınar, Uğur; Binici, Barış; Department of Civil Engineering (2010)
Deficient concrete structures are serious danger in seismic zones. In order to minimize economical and human loss, these structures should be retrofitted. Selecting suitable retrofitting schemes requires detailed investigation of these systems. Considering these facts, this study aims to calibrate analytical models of systems with chevron braces and internal steel frames; and evaluate their seismic performances. First, analytical models of the frames with braces and internal steel frames were prepared and t...
