Abstract

Tel halatlar ve demetler, mukavemetleri ve elastikiyetleri ile çoğu mühendislik disiplinlerinde önemli bir yer bulmuşlardır.Halatlar,
konstrüksiyonel avantajları nedeniyle, asansörler, vinçler ve köprülerde malzeme taşıma ekipmanı olarak sıklıkla kullanılırlar. Bu
çalışmanın amacı, sonlu elemanlar metodu ile eksenel çekme yüküne maruz bir öngerilmeli çelik demetin mekanik davranışını ortaya
koymaktır. İncelenen öngerilmeli demetin her kademesindeki burulma momenti, tel gerilmesi,tel birim şekil değiştirmesi ve emniyet
katsayıları tespit edilmiştir. Taşınan yüke göre sürtünmeli temas durumunda emniyet katsayısının 2.44, sürtünmesiz temas durumunda
2.39 olduğu sonucu çıkarılabilir.

Abstract

Wire ropes and strands have found an important place in many different engineering disciplines with their strengths and flexibilities.
Ropes are frequently used in elevators, cranes and bridges as material handling equipment due to their constructional advantages. The
purpose of this study is to reveal mechanical behavior of a prestressing steel strand subjected to axial tension load by means of finite
elements method. Twisting moment, wire stress, wire strain at each layer of investigated prestressing strand and safety factors have been
determined. It can be concluded that safety factors are 2.44 for frictional contact condition and 2.39 for frictionless contact condition
in accordance with total axial load carried.
