ST7-22.214.171.124 Cable Sag and Natural Frequency
This Webnote presents a parametric study of the relationship between the natural frequency of a cable and its degree of sag. As a cable is tensioned, generally the natural frequency will increase. Due to variability in cable installation tension (as well as thermal expansion), it is important to understand the range of natural frequencies produced for a given range of tension.
A steel cable of 240 m in length with a diameter of 80 mm is pinned on both ends but is held axially with a 20 kN/mm stiffness...
