Finite Elements Modeling and Analysis of an Axially Loaded Prestressing Strand

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.
