Hollow section profiles are widely used in the structural steel industry. An important point to take into consideration in such connections is the continuous transfer of internal forces from element to element. One of the measures taken to ensure this continuity is to use end plates. The connection between plates and elements is mainly provided by welds. The aim of this study is to determine an optimum weld thickness for connections subjected to local buckling of box-beam-columns under bending. Corner and circular fillet welds were used to join the designed plates with box columns and beams. Hollow section profile connections were experimentally studied in the Steel Structure Laboratory of the Department of Civil Engineering of Süleyman Demirel University. Results were used to develop numerical models. Ansys Workbench was used in numerical models to analyze the corner welds of different thicknesses and lengths depending on plate dimensions and to examine their behavior.

Kutu Kesitli Birleşimlerde Kaynak Kalınlığının Bölgesel Burkulma Davranışına Etkisi

Öz

Kutu kesitli profiller yapısal çelik endüstrisinde yaygın olarak kullanılmaktadır. Bu tür bağlantılarda dikkat edilmesi gereken önemli bir nokta iç kuvvetlerin elemandan elemana sürekli olarak aktarılmasıdır. Bu sürekliliğin sağlanması için alınan önlemlerden biri de ek plakaların kullanılmasıdır. Plakalar ve elemanlar arasındaki bağlantı esas olarak kaynaklarla sağlanır. Bu çalışmanın amacı, eğilme altında yerel burkulmaya maruz kalan kutu kolon- kiriş birleşimleri için optimum kaynak kalınlığının belirlenmesidir. Tasarlanan plakalar, köşe ve dairesel köşe kaynaklarla kutu kolon-kiriş birleşimlerinde kullanılmıştır. Kutu profil bağlantıları Süleyman Demirel Üniversitesi İnşaat Mühendisliği Bölümü Çelik Yapı Laboratuvarı'nda deneysel olarak incelenmiştir. Sonuçlar sayısal modeller geliştirmek için kullanılmıştır. Plaka boyutlarına bağlı olarak farklı kalınlık ve uzunluktaki köşe kaynaklarının analiz edilmesi ve davranışlarının incelenmesi amacıyla sayısal modellerde Ansys Workbench program kullanılmıştır.
