Bu çalışmada, Deprem Bölgelerinde Yapılacak Binalar Hakkında Yönetmelik 2007 (DBYBHY-2007) ve Türkiye Bina Deprem Yönetmeliği 2018 (TBDY-2018) esaslarına göre tasarlanmış 3, 6 ve 9 katlı toplam altı adet ters-V ve parçalı-X tipi merkezi çaprazlı çelik çerçevelerin (MÇÇÇ’lerin) dinamik performansları karşılaştırılmıştır. DBYBHY-2007 ve TBDY-2018’de tanımlanan 50 yılda aşılma olasılığı %2 olan en büyük deprem yer hareketine göre ölçeklendirilen uzak alan kayıtlı 44 adet deprem yer hareketi altında Opensees yazılımı kullanılarak toplam 1056 adet zaman tanım alanında doğrusal olmayan analizler gerçekleştirilmiştir. Elde edilen sonuçlar, hem ters-V hem de parçalı-X tipi MÇÇÇ’lerde TBDY-2018 esaslarına göre boyutlandırılan yapıların daha güvenilir olduğunu göstermiştir.

Comparison on Dynamic Performance of CBFs Designed as per TEC2007 and TEC2018

Öz

In this study, dynamic performance of six chevron and split-X braced concentrically braced frames (CBFs) having 3, 6 and 9 number of stories designed as per Turkish Seismic Code 2007 (TSC-2007) and Turkish Seismic Code for Buildings 2018 (TSCB-2018) were compared. By using Opensees software, a total of 1056 nonlinear time history analyses was conducted under 44 far-field ground motions scaled based on TSC-2007 and TSCB-2018 by considering maximum considered earthquake having a 2% probability of being exceeded in 50 years. The results indicate that the archetypes designed as per TSCB-2018 are more reliable in CBFs employing both chevron and split-X brace configuration.
