Çok Katlı Yapılarda Uniform Olmayan Burulma Nedeniyle Oluşan Tesirlerin Belirlenmesi için Bir Yöntem

Year 2015, Volume: 21 Issue: 3, 94 - 102, 01.07.2015

Abstract

Bu çalışmada, yüksek yapılarda yatay yükler etkisinde oluşan, Vlasov uniform olmayan burulması nedeniyle taşıyıcı yapı elemanlarda oluşan tesirlerin belirlenmesi için bir yöntem önerilmiştir. Bu yöntemde, mevcut yöntemlerde yapıya yüksekliği boyunca uniform yayılı bir yatay yük etkimesi kabulü yerine, daha gerçekçi olan kat seviyelerinde farklı büyüklüklere sahip yatay yüklerin etkimesi kabulü yapılmıştır. Önerilen yöntemde, herhangi bir enkesitin kesit özelliklerinin hesaplandığı ve birim çapılma diyagramının çizildiği bir algoritma hazırlanmış ve bu algoritma MATHCAD programında yazılmış ve böylece zaman alıcı diferansiyel denklem çözümüne gerek kalmadan kısa sürede sonuçların elde edilmesi sağlanmıştır. Yöntem Taranath, Smith ve Coull'un çalışmaları ile karşılaştırılmış, hassaslığını tespit için konsol bir kiriş ele alınarak ANSYS ve CONSTEEL analiz programları ile karşılaştırma yapılmıştır.

A method to Determine the Effects of Nonuniform Torsion on Tall Buildings

Year 2015, Volume: 21 Issue: 3, 94 - 102, 01.07.2015

Abstract

In this paper, a method is presented to determine the effects of Vlasov nonuniform torsion caused by horizontal loads on structural systems of tall buildings. In this method, a realistic assumption is made that the variable horizontal loads act at each story level instead of a uniform lateral load along the height of building. For the presented method, an algorithm is prepared in software MATHCAD in which the cross-sectional characteristics are calculated and the sectorial coordinate diagram is plotted. The results can be obtained in a short time, hence it is not needed to solve the time consuming differential equations. The method is compared with the studies of Taranath and Smith & Coul, and is also compared with the softwares ANSYS and CONSTEEL by modeling as a cantilever beam to check the accuracy of the algorithm.
