Yüksek Katlı Betonarme Binalarda Yanal Yük Dayanım Sistemleri

Öz

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

Lateral Load Resisting Systems in High-Rise Reinforced Concrete Buildings

Abstract

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