Abstract
Mevcut yapıların deprem performans, risk ve güçlendirme analizlerinde, yanındaki yapı ile olan ilişkisini uygun modelleme teknikleri ile analiz aşamasının içine dâhil ederek, sonuçların tekbaşına analiz edilmiş binalara göre olan farklılıklarını incelemek önemli bir konu olarak ortaya çıkmaktadır. Bu çalışmada, literatürdeki komşu binaların birbirleri ile olan etkileşim modelleri, statik itme analizi ve doğrusal olmayan hesap yöntemleri, deprem ivme kayıtlarının bir veri tabanından alınması ve tasarım spektrumuna göre ölçeklenmesi, zaman tanım alanına göre hesap yöntemi, hareket denkleminin Newmark-b yöntemi ile sayısal çözümü ve kırılganlık eğrileri ile bina performans seviyelerinin belirlenmesi konuları incelenmiştir. Bitişik (komşu) ve birbirine benzer binaların, deprem performanslarının birbirileri ile olan etkileşimli ve deprem yönüne göre değişen bir şekilde yapı blokları olarak ele alınıp, hasar görebilirlik-kırılganlık eğrileri yönünden değerlendirilmeleri incelenmiş ve binaların ayrı ayrı analiz edildikleri duruma göre daha farklı sonuçlar verdiği tespit edilmiştir.
The performance-based analysis for the low-storey building type structures are generally carried out, as those buildings were isolated single standing buildings with no interaction with adjacent buildings. Incorporating the interaction of the adjacent buildings in seismic performance and risk (retrofitting) analysis by using proper modelling techniques seems important by means of obtaining the deviation of the results from the conventional analysis results of isolated single modelled structures. Literature review has been carried out for the following topics; adjacent building models, push-over analysis, earthquake acceleration, time series database analysis and scaled records, time history analysis of equation of motion with Newmark-beta method and fragility curves for building performance levels. The aim of this study is the evaluation of vulnerability risk via fragility curves for seismic performance of adjacent buildings as interacting structures. Results show that interacted and isolated analysis types yields different seismic performance levels.
