Abstract

Deprem Bölgelerinde Yapılacak Binalar Hakkında
Yönetmelik Bölüm 7 de tanımlanan çatlamış kesit eğilme rijitliği ve performansa
dayalı çözüm için yapılacak  itme
analizinin başlangıcında kullanılacak rijitlik değeri, betonarme kesitlerin
göçme öncesi rijitliğinin olabildiğince gerçeğe yakın belirlenebilmesi konusuna
önem kazandırmıştır. Bu çalışmada betonarme kesitlerin değişik gerilme
evrelerindeki davranışları gözönüne alınarak, kesit rijitliğini etkileyen
özellikler yeniden incelenmiş, bulunan rijitliklerle elde edilen
yerdeğiştirmelerin deneysel verilerle karşılaştırılması yapılmış, elde edilen
sonuçlara dayanan bazı önerilerde bulunulmuştur.

Bending stiffness of reinforced concrete sections

Abstract

Bending stiffness of
cracked reinforced concrete sections defined by Turkish Earthquake Code Section
7 and bending stiffness to be used at the beginnig of push-over analysis,
increased the importance of a realistic determination of bending stiffness before
collapse.  In this study for considering
behaviour of reinforced concrete sections under various stress phases, the
factors effecting rigidity are revisited. Deflections obtained by using these
bending rigidities compared with the published results obtained in various
laboratory tests. Some proposals are made depending on the resuls of this work.

Keywords
