Abstract

Since lateral loads cause bending with high shear stresses in coupling beams, the structural behavior of a coupled shear walls is greatly affected by the behavior of the coupling beams which depends on its geometrical, mechanical properties and also coupling ratio (r). The value of r considered to be one of the major issues in nonlinear analysis in coupled shear walls represents the proportion of overturning moment resisted by the coupling action. In order to evaluate the r-values by using magnified beam algorithm, an adequate number of coupled shear walls having several geometries commonly used in construction were considered and then failure probabilities of coupling beams were calculated using Monte Carlo simulation

Bağ Kirişlerinin Göçme Olasılıklarının Monte Carlo Simülasyonu ile Belirlenmesi

Abstract

Yatay yükler bağ kirişlerinde eğilme ve beraberinde önemli oranda kesme gerilmelerine neden olduğu için, boşluklu perdeli sistemlerin yapısal davranışları bağ kirişlerinin geometrik, mekanik özellikleri ve bağ kirişi katkı oranı (r) ile yakından alakalı olan davranışlarından oldukça fazla etkilenmektedir. Bu nedenle, r-değerleri boşluklu perdeli sistemlerin doğrusal olmayan hesabında önemli bir parametre olarak düşünülebilir. Bu çalışmada “r” değerlerini belirlemek amacıyla uygulamada sıkça karşılaşılan geometriye sahip yeterli sayıda boşluklu perdeli sistemler dikkate alınarak bağ kirişi katkı oranları genişletilmiş çubuk teorisi yardımı ile ifade edilmiş ve Monte Carlo simülasyonu ile sözkonusu bağ kirişlerin göçme olasılıkları hesaplanmıştır

Keywords
