Concrete filled composite plate shear wall is an innovative structural lateral
force resisting system that is being investigated experimentally and
numerically. It consists of pre-fabricated steel web plates that are spaced
parallel to each other by having
regularly spaced cross-connecting tie bars (rods) which is then filled with
concrete. This paper make use of previously
developed numerical models and extends the study to investigate different
aspects of wall behavior. In this study, two of the previously tested wall
models were used to investiagete percentage of steel plate yielding at certain
wall elevations per certain drift levels, steel plate von-Mises stress contours,
the distribution of cracks in concrete, relative contribution of steel plates
and concrete to total wall base shear and axial stress distribution of steel
plate and concrete. The study assumes fixed-based walls and describes the
development of finite element models using LS-Dyna.

Beton Dolgu Kompozit Levha Perde Duvaların Sonlu Elemanlar Metodu Kullanılarak İncelenmesi

Öz

Beton dolgu kompozit levha perde duvar, deneysel ve sayısal
olarak araştırılan yenilikçi bir yapısal yanal kuvvet direnç sistemidir.
Önceden imal edilmiş çelik levhaların birbirine paralel yerleştirilerek
bağlantı çubukları ile bağlanması ve levhalar arasındaki boşluğun beton ile
doldurulması ile meydana gelir. Bu makalede, daha önce geliştirilmiş sayısal
modellerden yararlanılmakta ve duvar davranışının farklı yönlerini araştırmak
için çalışmayı genişletmektedir. Bu çalışmada, daha önce test edilmiş iki duvar
modeli kullanılarak; belli duvar yüksekliğideki çelik levhaların belli ötelenme
oranına göre akma oranı, çelik levha von-Mises gerilme dağılımları, çatlakların
beton üzerindeki dağılımları, çelik levha ve betonun toplam duvar taban kesme
kuvvetleri üzerindeki oransal katkıları 
ve çelik levha ve betonun eksenel gerilme dağılımları incelenmiştir.
Çalışmada, sabit mesnetli duvarlarlar varsayılmakta ve sonlu eleman
modellerinin LS-Dyna kullanılarak oluşturulması açıklanmaktadır.
