BETONARME BİR ELEMANDA EGRİLİK SÜNEKLİLİĞİNİN İNCELENMESİ- EVALUATION of CURVATURE DUCTILITY on a REINFORCED CONCRETE MEMBEREVALUATION of CURVATURE DUCTILITY on a REINFORCED CONCRETE MEMBER

BETONARME BİR ELEMANDA EGRİLİK SÜNEKLİLİĞİNİN İNCELENMESİBu çalısmada, betonarme bir elemanın egrilik sünekligi ve sünekligi etkileyen faktörlerin arastırılmasıamaçlanmıstır. Bu sebeple sargılı ve sargısız beton modelleri literatürdeki çalısmalardan alınarak ayrı ayrıincelenmistir. Ayrıca sargı etkisini etkileyen faktörler de dikkate alınmıstır. Betonarme kesitlerdeki sünekligiincelemek üzere SEMAp programından yararlanılmıstır. SEMAp programında 51 adet numunenin, degisikparametreler etkisinde, moment-egrilik diyagramlarından yararlanarak süneklik degerleri hesaplanmıstır.Elde edilen sonuçlar yardımıyla, SAS programından yararlanarak bir süneklik denklemi elde edilmistir.Örneklerde yapılan degisikliklerin süneklige etkileri sonuç bölümünde ayrıntılı olarak verilmistir. Ayrıcayapılan kontroller sonucunda elde edilen denklemin kullanılabilir oldugu ortaya çıkmıstır.Anahtar sözcükler: Moment-egrilik, Sargılı ve sargısız beton modelleri, Süneklik, Süneklik denklemiEVALUATION of CURVATURE DUCTILITY on a REINFORCED CONCRETE MEMBERIn this study, investigation of curvature ductility of a reinforced concrete member and the factorswhich effect the ductility are purposed. Therefore, confined and unconfined concrete models are taken fromstudies in the literature and analysed one by one. Furthermore, the factors that effect the confinementbehavior are also taken into consideration. An analysis program named SEMAp is used to investigate theductility on reinforced concrete sections. Ductility values of 51 different specimen which are under the swayof different parameters are calculated by using moment-curvature diagrams by SEMAp analysis program. Anew equation has been improved by using SAS statistic program with the help of the obtained results. At thelast part of the study, effects of different parameters on ductility, are given with details. Moreover, it isdetected that, the equation which is obtained after several verifications, gives acceptable results.
