Zayıf Kolon - Güçlü Kiriş Birleşiminde Kesme Çivili Levhanın Etkisi

Year 2009, Volume: 1 Issue: 1, 7 - 10, 15.01.2009

Abstract

Betonarme yapılarda genis kullanım alanları yaratmak gibi çesitli sebeplerden dolayı kolonlar kirislerden daha zayıf yapılmaktadır. Bu durumda, deprem etkisi altında klasik yapılarda büyük sorunlar olusmakta, bina ya agır hasar görmekte yada göçmektedir. Bu sorunları ortadan kaldırmak için yapılmıs olan bu çalısmanın amacı zayıf kolon-güçlü kiris birlesiminin kesme ve egilme kapasitesini arttırmaktır. Bunun için, birlesim bölgesinde kesme çivili levhalar kullanılmıstır. Bir adet takviyesiz sahit ve bir adet deney elemanı olmak üzere toplam iki adet deney elemanı test edilmistir. Deney elemanları, bir çerçevenin dıs dügüm noktasından elde edilmistir. Kontrol deney elemanı dügümde olusan kesme hasarı sonucu göçmüsken, diger deney elemanı sünek bir davranıs göstererek kiris dibinde egilmeden göçmüstür.

Zayıf Kolon - Güçlü Kiriş Birlesiminde Kesme Çivili Levhanın Etkisi

Abstract

In reinforced concrete structures, columns are made weaker than beams due to various reasons like creating wider spaces for use. In this situation bigger problems occur in classical structures under earthquake effect such as the building is either severely damaged or collapsed. The aim of this study is to increase the shear and bending capacity of weak column-strong beam connection and it can be a good alternative in order to overcome the problems mentioned above. For this, on the column, steel plates with shear stud are used at the connection. One control and one test specimen are tested. The specimens are derived from the exterior joint of a frame. We observed that the control specimen is collapsed due to the joint failure whereas the other test specimen showed ductile behavior and collapsed by bending in the bottom of the
beam.
