EFFECT OF BUCKLING RESTRAINED STEEL BRACES ON NONLINEAR BEHAVIOR OF REINFORCED CONCRETE STRUCTURES

Öz

Buckling Restrained Braces are useful structural components when providing bracing for seismic or other loads. Buckling Restrained Braces which have a large ductility capacity are helped to decrease the plastic deformations due to seismic loadings. Although the literature information is limited for the reinforced concrete structures, frame with Buckling Restraint Braces are being used for a new and existing reinforced concrete buildings. In this study, Buckling Restraint Braces which are implemented to reinforced concrete sample structures having different number of stories (low/medium-rise) with different configurations are examined using nonlinear static analysis process. depremlerin ülkemiz ekonomisinin en az zarara oluşması

BETONARME YAPILARDA BURKULMASI ÖNLENMİŞ ÇELİK ÇAPRAZ ELEMANLARIN DOĞRUSAL OLMAYAN DAVRANIŞA ETKİSİ

Öz

Burkulması önlenmiş çaprazlar, sismik ve/veya diğer yükler altında gerekli dayanımı sağlamak üzere kullanılan kullanışlı yapı elemanlarıdır. Önemli oranda süneklik kapasitesine sahip bu elemanlar deprem durumunda oluşan plastik şekil değiştirmelerin azaltılmasına da yardımcı olur. Her ne kadar literatürde yeterli bilgi olmasa da, yeni betonarme binaların tasarımında veya güçlendirme amaçlı olarak mevcut betonarme binalarda Burkulması önlenmiş çapraz elemanlar ile çerçeveler beraber kullanılabilmektedir. Bu çalışma kapsamında farklı kat sayılarına sahip (az/orta katlı) örnek betonarme yapılarda farklı şekilde uygulanmış Burkulması önlenmiş çapraz elemanlarla birlikte çerçeve davranışı doğrusal olmayan statik analiz ile incelenmiştir

Anahtar Kelimeler
