Özet

BETONARME BİR ELEMANDA EGRİLİK SÜNEKLİLİĞİNİN İNCELENMESİ Bu çalısmada, betonarme bir elemanın egrilik sünekligi ve sünekligi etkileyen faktörlerin arastırılması amaçlanmıstır. Bu sebeple sargılı ve sargısız beton modelleri literatürdeki çalısmalardan alınarak ayrı ayrı incelenmistir. Ayrıca sargı etkisini etkileyen faktörler de dikkate alınmıstır. Betonarme kesitlerdeki sünekligi incelemek üzere SEMAp programından yararlanılmıstır. SEMAp programında 51 adet numunenin, degisik parametreler 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. Ayrıca yapılan kontroller sonucunda elde edilen denklemin kullanılabilir oldugu ortaya çıkmıstır.

Therefore, confined and unconfined concrete models are taken from studies in the literature and analysed one by one. Furthermore, the factors that effect the confinement behavior are also taken into consideration. An analysis program named SEMAp is used to investigate the ductility on reinforced concrete sections. Ductility values of 51 different specimen which are under the sway of different parameters are calculated by using moment-curvature diagrams by SEMAp analysis program. A new equation has been improved by using SAS statistic program with the help of the obtained results. At the last part of the study, effects of different parameters on ductility, are given with details. Moreover, it is detected that, the equation which is obtained after several verifications, gives acceptable results.
