Bir
tür metalik sönümleyiciler olarak kabul edilen Burkulması önlenmiş Çaprazlar
(BÖÇ) önemli depremlerde çekme ve basınçta akarak dengeli bir histeretik
davranış gösterirler. Bu çalışmada farklı çelik uç detayı malzemesine sahip
BÖÇ’lerin yön değiştiren tekrarlı yükler altındaki histeretik davranışına
ilişkin deneysel bulgu ve değerlendirmeleri verilmektir. Denenen BÖÇ’ler için
kuvvet-yerdeğiştirme histeretik eğrileri, histeretik enerji yutma miktarları ve
etkili sönüm oranları hesaplanarak karşılaştırmalar yapılmıştır. Özgün detaylar
ile üretilen ve denenen BÖÇ’lerin yeterli bir performans gösterdiği ve bu
performansının ileride yapılabilecek çalışmalarla iyileştirilebileceği sonucuna
varılmıştır.

Anahtar Kelimeler

Çelik, burkulması önlenmiş çapraz (BÖÇ), histeretik enerji, etkili sönüm oranı
