Çelik Çekirdekli Burkulması Önlenmiş Çaprazların (BÖÇ) Tasarımı, Üretimi ve Deneysel İncelenmesi

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
