THE BEHAVIOUR OF TWISTED TALL BUILDING STRUCTURES UNDER LATERAL LOADS

Abstract

Twisted tall building structures have recently been used as an architectural and structural form. On the other hand, there are very few studies on the behavior of twisted tall buildings under seismic and wind lateral loads. In this paper, the behavior of twisted tall buildings under seismic and wind-induced loads is investigated and compared with their prismatic counterpart. As a case study, a twisted building in Miami, Florida, is modified by twisting all floor levels with an angle of 3 degrees. Lateral wind forces and seismic forces are considered for this location and using ASCE 7-16. The 3-dimensional models are created using ETABS for analysis. The structural system of the building consists of a composite core system. The floor system consists of a post-tensioned concrete slab and the surrounding twisted columns are reinforced concrete. For the analysis of twisted tall building structures under lateral loads such as wind loads and seismic loads, the application of provisions and the behavior of prismatic and twisted tall building structures are discussed. In the study, it was found that the lateral stiffness of the twisted tall building under seismic loads is lower than that of the prismatic tall building.

BURGULU YÜKSEK YAPILARIN YANAL YÜKLER ALTINDA DAVRANIŞI

Öz

Burgulu yüksek bina yapıları son dönemlerde mimari ve yapısal bir form olarak kullanılmaktadır. Öte yandan, burgulu yüksek yapıların, deprem ve rüzgar yükleri altında yanal yükler olarak davranışına ilişkin çok az çalışma bulunmaktadır. Bu çalışmada, burgulu yüksek katlı yapıların deprem ve rüzgar yükleri altındaki davranışı incelenmiş ve emsali olan prizmatik yapı ile karşılaştırılmıştır. Bir vaka analizi olarak, Miami, Florida'da bulunan burgulu bir yüksek bina, tüm katları 3 derecelik bir açıyla döndürülerek düzenlenmiştir. Binanın bulunduğu konuma göre yanal kuvvetler rüzgar ve sismik kuvvetler dikkate alınmış ve ASCE 7-16 yönetmeliği kullanılmıştır. ETABS kullanılarak analiz için 3 boyutlu modeller oluşturulmuştur. Bina taşıyıcı sistemi, betonarme kolonlu kompozit bir çekirdek sisteme sahiptir. Döşeme sistemi ardgermeli betonarme döşemeye sahiptir ve burgulu kolonlar betonarmedir. Rüzgar yükleri ve sismik yükler gibi yanal yükler altında burgulu yüksek bina yapılarının analizi için, yönetmelik hükümlerinin uygulanması ve prizmatik, burgulu yüksek bina yapılarının davranışı kıyaslamalı olarak tartışılmıştır. Çalışmada, deprem yükleri altında burgulu yüksek binanın yanal rijitliğinin prizmatik yüksek binaya göre daha düşük olduğu tespit edilmiştir.
