Yüksek Katlı Betonarme Binalarda Yanal Yük Dayanım Sistemleri

Verimli ve ekonomik bir yüksek bina, yapısal sistemin seçimini etkileyen önemli faktörler tam olarak anlaşılmadan ve bu sisteminmimari, mekanik ve diğer yönlerle nasıl bir ilişki içinde olacağı bilgisi olmadan tasarlanamaz. Bu çalışmada, farklı tipteki yanal yükdirençli sistemlerin (moment çerçeve sistem, perde duvarlı sistem, perdeli-çerçeveli sistem ve tüplü çerçeve sistemler) sismik yüklerve rüzgâr yükleri altında yapısal tepkilerini karşılaştırmak için bir yapısal analiz programı olan ETABS kullanılarak yapısal analizleryapılmıştır. Bina 625m² (25m x 25m) alana sahip 28 kattan oluşmaktadır. Tüm yanal yük dirençli sistemler için kat deplasmanlarıhesaplanmıştır. Yanal yük dirençli sistem tipleri arasında perdeli-çerçeveli sistem, bu yükseklik için çok uygun bir yapısal tepkigöstermiş ve sınır değerlerini aşmamıştır.

Lateral Load Resisting Systems in High-Rise Reinforced ConcreteBuildings

An efficient and economical tall building cannot be designed without a thorough understanding of the significant factors affecting theselection of the structural system and knowledge of how the structural system will interrelate with architectural, mechanical and otheraspects. In this study, structural analyses were performed to compare the structural response of different types of lateral load resistingsystems (moment-resisting frame system, shear wall system, dual system and framed tube system) under effect of seismic and windloads using the structural program ETABS. The building consists of 28 stories with area of 625m² (25m x 25m). Storey displacementswere evaluated for all lateral load resisting systems. Among the types of lateral load resisting systems, dual system showed a verysuitable structural response for this height and did not exceed the limitation values.
