Abstract:

 Concentrically braced frames CBF are the types of frames used effectively to carry lateral loads. These frames transfer horizontal loads with braces and their rigidity are quite high compared to moment resisting frames. Therefore, it is typically used in earthquake zones. In this study 3, 5 and 8 storey inverted-V braced frames are considered in order to examine the seismic behavior of brace sections. The brace members of the frames are designed using three different cross-section types as I, box and pipe sections. A total of nine parameters, three different storey and three different braces sections, were used. Accordingly, nine CBFs were designed and time history and static pushover analyzes were performed. seismic performances of the frames were evaluated with findings. It can be said that the most advantageous brace section type is pipe, box and I section, respectively.

 Merkezi çaprazlı çerçeveler MÇÇ yatay yüklerin taşınmasında etkin olarak kullanılan çerçeve türleridir. Bu çerçeveler yatay yükleri çapraz elemanları ile aktarırlar ve çaprazsız çerçevelere göre rijitlikleri, yük taşıma kapasiteleri oldukça yüksektir. Bu nedenle deprem bölgelerinde de sıklıkla kullanılmaktadır. Bu çalışmada; çapraz eleman kesitlerinin deprem etkisi altında davranışını incelemek amacıyla 3, 5 ve 8 katlı ters-V merkezi çaprazlı çerçeveler ele alınmıştır. Ele alınan çerçevelerin çapraz elemanları I, kutu ve boru kesit olmak üzere üç farklı kesit tipinde tasarlanmıştır. Üç farklı kat sayısı ve üç farklı çapraz eleman kesiti olmak üzere toplam 9 adet parametre kullanılmıştır. Buna göre 9 adet MÇÇ tasarlanmış ve statik itme analizleri ile zaman tanım alanında dinamik analizleri yapılmıştır. Elde edilen analiz sonuçları ile birlikte çerçevelerin deprem etkisi altındaki performansları değerlendirilmiştir. Buna göre en avantajlı çapraz eleman kesitlerinin sırasıyla boru, kutu ve I kesit olduğu söylenebilir.
