Malzeme
modelleri yapıların sismik analizlerinde önemli rol oynamaktadır. Literatürde,
betonarme yapılarda kullanılan malzemelerin gerilme-şekil değiştirme ilişkisini
tanımlamak için çeşitli malzeme modelleri bulunmaktadır. Beton ve çelik gibi
iki farklı yapı malzemesinin bir arada kullanılması ile elde edilen betonarme
yapılarda malzeme modelleri ayrı bir öneme sahiptir. Hem beton hem de çelik
için kullanılan farklı malzeme modellerinin karşılıklı etkileşimi çalışmanın
konusunu oluşturmaktadır. Çalışmanın amacı betonarme yapılarda kullanılan
farklı malzeme modellerinin birbirleri ile uyumlu olup olmadığını kontrol
etmektir. Bu çalışmada dörder farklı beton ve çelik malzeme modeli dikkate
alınarak seçilen iki katlı betonarme bir yapı için hesaplamalar yapılmıştır.
Her bir malzeme modeli için X ve Y doğrultularında taban kesme kuvveti –
deplasman eğrileri elde edilmiştir. Çalışmada dikkate alınan malzeme modelleri
hakkında bilgiler verilmiştir. Farklı malzeme modelleri arasında bir uyum
olduğu gözlemlenmiştir. Bu malzeme modellerinin birlikte kullanılabilirliğini
ortaya koymuştur.
