Abstract

Kolon-kiriş birleşimleri yapı
açısından oldukça önemlidir. Rijit veya mafsallı gibi basitleştirmeler yapılsa
da, gerçek davranış farklıdır. Kolon kiriş birleşimlerin gerçek davranışı yarı
rijit olarak tanımlanmaktadır. Yarı rijit birleşimlerin ana karakteristik
özelliği doğrusal olmayan davranışıdır. Bu çalışmada düşey berkitmeli alın
levhalı birleşimlerin moment dönme karakteristikleri deneysel olarak
incelenmiştir. Önerilen metotta berkitmeler başlık ve gövdeye
kaynaklanmıştır.  Farklı alın levha
kalınlıkları için önerilen birleşimin göçme şekilleri, moment-dönme eğrisi ve
karakteristikleri karşılaştırmalı olarak incelenmiştir. Ayrıca, bu birleşime
yakın davranış gösteren ve aynı levha kalınlıklarına sahip kiriş gövdesine alın
levhalı birleşimlerle önerilen tipteki birleşimlerin deney sonuçları
karşılaştırmalı olarak değerlendirilmiştir.

Investigation of Experimental Analysis on Behaviour of End-Plate Beam to Column Connections with Vertical Stiffener

Abstract

The
beam to column connections are very important for the structural point of
view.  However, the simplifications like
rigid or hinged type joints, the real behavior and the idealized ones are
different. The realistic behaviors of the beam to column connections are
described as semi-rigid. The main characteristic of the semi-rigid connection
is its nonlinear behavior. The moment rotation characteristics of the
vertically stiffened end plate connections are experimentally, investigated.
The proposed method is to weld the stiffeners to the web and flange of the
beam. The failure modes, the moment-rotation curves, and the characteristics
are examined in comparison for variable end plate thickness. Moreover, the end
plate connections, welded to
web of the beam, with similar behavior, with same thickness, are investigated
and compared parallel with
the proposed ones.
