Kaiser Cıvatalı Moment Birleşimlerin Avrupa Çelik Profilleri ile Tasarımı

Öz

Kaiser Cıvatalı Moment birleşimler yüksek sünek çelik çerçeveler için Amerika Birleşik Devletleri’nde yaygın olarak kullanılmakta ve deneysel çalışmalar ile performans yeterliği kanıtlanmış birleşimler arasında AISC358-16’da yer almaktadır. Ancak Kaiser cıvatalı moment birleşimlerine TBDY-2018’de yer verilmemiştir. Bu çalışmada Türk ve Avrupalı inşaat mühendislerinin istifadelerine sunmak amacı ile deprem yükleri altında yüksek performansa sahip olan Kaiser Cıvatalı Moment birleşimleri tasarım adımlarında Avrupa profili ve çelik kalitesi ile çalışılmıştır. Kolon ve kiriş bölgesi için gerekli tüm kontroller açıklanmış ve sayısal bir örnek sunulmuştur. Tasarım parametrelerinin tüm tasarım üzerine etkisini incelemek amacıyla bir hesap algoritması ve bir excel programı oluşturulmuştur. Kiriş kesitinin ve braketin geometrik özelliklerinin birleşim davranışı üzerine etkisi incelenmiş ve bu etkiler grafikler ile sunulmuştur.

Design of Kaiser Bolted Bracket Moment Connections with European Steel Profiles

Abstract

Kaiser Bolted Bracket (KBB) Moment Connections are widely used for Special Moment Frames in USA and these connections are accepted as pre-qualified moment a connection which means satisfactory performance capacity was proved with experimental studies under earthquake load and take place in AISC358-16. However, this connection type does not take place in Turkish Building Design Code (TBDY-2018) as recommended moment connection for Special Moment Frames. In this study, it was aimed to illustrate design steps of high-performance KBB Moment Connections were studied with European steel shapes and steel quality for utilization of Turkish and European structural engineers. All designed steps for both column side and beam side were explained and a numerical example was presented. A calculation algorithm and an excel design program were developed to investigate the effect of design parameters on whole design process. The effect of beam size and bracket geometry on design process were determined and presented as graphical illustration.
