Abstract

Buckling restrained braces (BRBs) have high energy dissipation capacity and equal tension and compression axial load capacity. Therefore, the application of BRBs has gained popularity in seismic regions. The first studies on BRBs started in Japan in 1970 and since then more studies have been undertaken in other earthquake prone countries. Although the BRBs perform well in component and subassembly tests, they do not perform as well in frame tests because of the interaction between beam-column-gusset plate and BRB. In this study, the component and subassembly test of the BRBs and then BRB frame tests available in the literature are summarized.

Özet

Burkulması engellenmiş çelik çaprazların (BEÇÇ’lerin) eksenel basınç ve çekme kapasiteleri eşit olmasının yanında BEÇÇ’ler yüksek enerji sönümleme özelliğine de sahiptirler. Bu bakımdan deprem bölgelerinde kullanılmaları giderek artmaktadır. BEÇÇ’lerin geliştirilmesine ait çalışmalar ilk olarak 1970’li yıllarda Japonya’da başlamıştır ve daha sonra özellikle deprem bölgesi üzerindeki ülkelerde devam etmiştir. BEÇÇ’lerin eleman ve çerçeve benzeri sistem bazındaki performanslarının oldukça kararlı olmasına karşın, çerçeve sistemi içerisindeki davranışlarında kiriş, kolon, bayrak levhası ve BEÇÇ arasında meydana gelen etkileşimden dolayı istenmeyen sonuçlar elde edilmiştir. Bu çalışma, BEÇÇ’lerin ilk olarak eleman ve çerçeve benzeri sistem bazında ve daha sonra çerçeve içerisinde yapılan deneysel çalışmaları özetlemektedir.
