Abstract
Son yıllarda Türkiye' de meydana gelen depremler, insanların içinde yasam faaliyetlerini devam ettirdikleri yapı stogunun deprem karsısında ayakta kalıp kalmayacagına dair durumunu tespit etme ihtiyacını ortaya çıkarmıstır. Deprem kusagı üzerinde olan Türkiye' de, binaların deprem risklerinin bilinmesi için gerekli olan çalısmaların zaman ve maliyet gerektirdigi görülmüstür. Bu çalısmaların kısa zamanda az maliyetle yürütülebilmesi için çesitli hızlı degerlendirme yöntemleri ortaya konulmustur. Bu tez çalısmasında betonarme binaların göçme riskinin saptanabilmesi için mevcut hızlı degerlendirme yöntemlerinden 4 ayrı yöntem seçilmistir. Seçilen yöntemler, 1999 Kocaeli depreminde orta hasarlı örnek bir binaya uygulanmıstır. Örnek binanın orta hasar durumunu ile örtüsen en uygun yöntem belirlenmeye çalısılmıstır. Bes bölümde sunulan çalısmanın birinci bölümünde konuya giris yapılmıstır. Çalısmanın ikinci bölümünde konu ile ilgili önceden yapılmıs 4 ayrı hızlı degerlendirme yöntemi anlatılmaktadır. Üçüncü bölümde önceden yapılmıs bir çalısmadan bahsedilmektedir. Burada konu ile ilgili önceden yapılmıs degerlendirme yöntemleri ile göçme riskinin saptanacagı örnek bina bilgileri verilmekte olup, örnek binanın Japonya Mimarlık Enstitüsü - SBG indeksleri ile deprem kapasitesi incelenmektedir. Ayrıca örnek binanın dogrusal olmayan dinamik ve statik çözümlemesinden ve sonuçlarından bahsedilmektedir. Çalısmanın dördüncü bölümünde ikinci bölümde anlatılan 4 ayrı hızlı degerlendirme yöntemi üçüncü bölümde bilgileri verilen örnek bina üzerinde uygulanmaktadır. Çalısmanın sonuç bölümünde, örnek binanın orta hasar durumu ile örtüsen en uygun hızlı degerlendirme yöntemi belirlenmistir. Dogrusal olmayan statik ve dinamik çözümlemelerle uyumlulugu karsılastırılmıstır. Ayrıca Türkiye' deki betonarme binaların deprem performanslarına göre sınıflandırılmasına yönelik ileri çalısma önerisinden bahsedilmistir.
Due to the recent destructive earthquakes in Turkey, the need has arisen to determine whether existing building stock in which our people continue their lives will survive an earthquake. It has been seen that in Turkey, which exists on the seismic belt that efforts necessary to know earthquake risks of the buildings require time and cost. Various methods were developed to pursue such works within the shortest time and at minimum cost. In this thesis, four different methods of rapid assessment were selected, those were developed to detect the risk of collapse of the reinforced concrete buildings. The selected methods were applied on a building with a medium damage after by 1999 Kocaeli earthquake. The most appropriate method corresponding to the medium damage of the example building was determined. An introduction to the subject was made in the first chapter of this study submitted in five chapters. In the second chapter of the study, four different rapid assessment methods developed here explained. In the third chapter, some information is provided about a study made previously. Information is provided on sample building collapse risk of which are to be determined using the previously developed evaluation methods related to the subject, and the earthquake capacity of the sample building with Japan Architectural Institute ? SBG indexes is examined. Besides, nonlinear dynamic and static solutions and results of the example building are given. In the fourth chapter of the study, the four different rapid assessment methods are explained in the second chapter are applied on the given example building. In the conclusion most appropriate method for the given method corresponding to the medium damage of the example building was determined. Its compliance with the nonlinear static and dynamic analyses is compared. Besides, a further study suggestion was mentioned for classification of the reinforced concrete buildings in Turkey according to their earthquake performance
