Öngerilmeli Halatlı Çatı Sistemleri Beşiktaş Stadı Tasarım Kriterleri

Öz

Bu çalışmada halatlı çatı sistemi ile inşa edilmiş Beşiktaş İnönü Stadı tasarım kriterlerine yer verilmiştir. Bu tür yapılarda taşıyıcı sistem seçimi, yapıya etkiyen yüklerin belirlenmesi ile yapısal elemanların analiz ve tasarım prosedürleri açıklanmıştır. Stadyum yapısının geometrisi Yapının statik ve depremli durum analizi için oluşturulan sonlu elemanlar modelinde yapılan kabuller ve analiz modeli ile ilgili detaylarda bu makale kapsamında sunulmuştur. Çatı geometrisinde uyulması gerekli kriterler halatlı çatı sistemi yapılması gerekliliği matematik modellerin özetinden oluşmaktadır. Bisiklet tekerleği mekanik çalışma prensibini örnek alan stadın çatı sistemi tasarımında öngerilmeli halatlı çatıların çatı ring kirişi ve üstten ankastre aşağıdan mafsallı kolon elemanları kullanılarak olası bir depremde çatıdan aktarılacak yatay yüklerin minimizasyonu ve davranış modellemesi özetlenmiştir. Ayrıca çatı ve üzerine oturduğu betonarme stad yapısı arasındaki dinamik karekteristikleri yansıtan çalışma rüzgar tünel testi sonuçları özet halinde verilmiştir.

Pretensioning Cable Roof Systems Besiktas Stadium Design Principles

Abstract

In this study, design criteria of Besiktas Inonu Stadium, and the roof with a prestressed rope system, are included. Selection of systems in these structures, determination of the loads affecting the structure, analysis and design procedures of structural elements are explained. The geometry of the stadium structure, the assumptions made in the model for static and seismic analysis of the structure and the details of the analysis model are presented with this article.  the necessity of building a rope roof system consists of a summary of mathematical models for the design criteria of the roof. For the roof design of this stadium which basically takes the mechanical working principle of a bicycle wheel as a starting point, the minimization and behavior modeling of the horizontal loads which can be transferred from the roof to the structure in a possible earthquake are summarized in this article including the wind tunnel test.
