The Effect of Welding Length of Semi-Rigid Connections With Top and Seat Angles

Abstract

Taking into account the behavior of connection in analysis and design of steel frames is important due to presenting the actual behavior of frames. So, the behavior of the connections should be well known. The connections form various moment-rotation curves according to the type of connection, the elements of connection and the shape of placement. These curves are visual expressions of the actual behavior that has been obtained from experiments. The experiments of some connections have been obtained partially and has been formed the databank. It has been done the classi cation and formed models by this databank to express the behavior of connection. To determine the behavior of the connection, the various connection experiments which are different from the connection with top and bottom angle in the literature are done in this thesis. The use of stiffeners in top and bottom angle and web of the connection with the top and bottom ange angle and different weld length in top and bottom angle is suggested.

Alt ve Üst Korniyerlerli Yarı-Rijit Birleşimlerde Kaynak Boyu Etkisi

Abstract

Çelik yapıların analiz ve dizaynında birleşim davranışının hesaba katılması, yapının gerçek davranışını temsil edebilmesi açısından önemlidir. Dolayısıyla, birleşim davranışının iyi bilinmesi gerekir. Birleşimler, birleşim tipine, yerleşim biçimlerine ve elemanlarına göre değişik moment-dönme eğrileri oluştururlar. Bu eğriler deneylerle elde edilen gerçek davranışın mühendislik bakış açısıyla görsel anlatımıdır. Bazı birleşimler için bu deneyler kısmen yapılmış, çeşitli veri bankaları oluşturulmuştur. Bu veri bankalarından yola çıkılarak birleşimin davranışını analizde ifade edebilmek için sını andırmalar yapılmış ve modeller oluşturulmuştur. Bu araştırma kapsamında literatürde olan mevcut alt-üst başlık korniyerli birleşimlerden farklı olarak alt-üst başlık korniyerlerinde ve kiriş gövdesinde berkitme kullanımı önerilmiş ve alt üst korniyerlerde kullanılan berkitmelerdeki kaynak boyu etkisi incelenmiştir.
