Çeşitli yapı tipleri için izin verilebilir farklı oturma sınırlarının derin kiriş modeli ile belirlenmesi

Zemin-yapı etkileşimi problemlerinde, temellerde oluşan farklı oturmalar, hasarlarda etkin olan faktörlerin başında gelir. Bu sebeple, özellikle 1950’li yıllardan itibaren, birçok araştırmacı tarafından izin verilebilir hareket sınırlarını belirleyen kriterler ortaya konmaya çalışılmış, fakat özellikle problemi etkileyen çok sayıda değişken sebebiyle bu kriterler üzerinde tam bir anlaşma sağlanamamıştır. Bu çalışmada, öncelikle literatürdeki izin verilebilir farklı oturma tanımları ve bu tanımlara ilişkin sınırlar gözden geçirilmiş, ardından çok sayıda vaka analizi Burland ve diğerleri [1] tarafından önerilen hasar seviyeleri ve derin kiriş modeli [2] ışığında incelenmiştir. Yapılan analizler sonucunda, çerçeveli ve yığma yapılar için izin verilebilir farklı oturma sınırları, çeşitli yapısal hasar seviyelerine karşılık gelen açısal çarpılma değerleri cinsinden ifade edilerek güncellenmiştir.

Estimation of allowable differential settlements for various structure types using deep beam analogy

In soil-structure analysis problems, differential settlements are regarded as one of the major sources of building damage. For this reason, starting from 1950s, various researchers have come up with criteria, which determine allowable movements of structures. However a total agreement on these criteria could not be reached, especially due to numerous variables that have effect on this problem. In this study, first the terms that are being used to define differential settlements have been reviewed, and then a large database of case histories was examined using the damage criteria proposed by Burland [1] and the deep beam analogy. The analyses resulted in updated allowable angular distortion values for framed buildings and buildings with load-bearing walls, for different target damage levels.
