Betonarme yapı sistemlerinde dolgu duvarlar yaygın bir şekilde kullanılmaktadır. Dolgu duvarların
yapıya sadece olumlu etkisinin olacağı ve bu etkiyi rezerv tutma düşüncesiyle, genellikle konvansiyonel
analiz programlarında dolgu duvarlar salt düşey yük olarak çerçeveye etki ettirilmektedir. Oysaki yaşanan
depremler sonrası yapılan araştırmalar, dolgu duvarların betonarme çerçeveye olumlu/olumsuz etkilerinin
olduğunu göstermektedir. Dolgu duvar etkisinin modele yansıtılmaması, tasarımcıların yaptığı analizlerde
çeşitli yapısal düzensizlikleri de görememesine neden olabilmektedir. Bu çalışmada, mevcut bir yapı
seçilmiş ve öncelikle dolgu duvarlar salt düşey yük (DY) olarak ideCAD yapı analiz programında
modellenmiş daha sonra dolgu duvarlar DY ve hem düşey yük hem de eşdeğer basınç çubuğu (DY+EBÇ)
olarak Sap2000 yapı analiz programında oluşturulmuştur. Sap2000’deki DY+EBÇ modeli DY modeli ile
mukayese edildiğinde; yapı performansının arttığı, burulma ve yumuşak kat gibi düzensizlik değerlerinin
değiştiği görülmüştür.
Infill walls are widely used in reinforced concrete building systems. With the idea that the infill
walls will have only positive effect on the structure and reserve this effect, the infill walls are generally
affected in the frame as a vertical load in conventional analysis programs. However, after the earthquakes
researches show that the infill walls have positive / negative effects on the reinforced concrete frame.
Failure to reflect the infill wall effect on the model may cause the designers not to see various structural
irregularities in their analysis. In this study, an existing structure was chosen and firstly infill walls were
modeled in ideCAD structure analysis program as vertical load (DY) and then infill walls were formed as
DY and vertical load and equivalent compression strut (DY + ETC) as Sap2000 structure analysis
program. DY + EBÇ model in Sap2000 compared to DY model; It was observed that the structure
performance increased and torsional and soft floor values changed.
