Studies on Cable’s Parameters Based on the Cable-Truss Mixed Model
The steel strand cables can effectively stand for the horizontal wind load, enhance the lateral stiffness of the lifting stand, reduce the horizontal displacement of the tower and improve the overall stability. Based on a cable-truss mixed finite element model, in which the cables are simulated via the equivalent elastic modulus method, cable’s parameters, including the tilt angle, initial stress and layout of cables are analyzed. With the increasing of initial stress of cables, the lateral stiffness and overall stabalitily of the structure is improved greatly. And a certain range of tilt angle can effectively enhance the overall mechanical performances, insufficient or overlarge tilt angle are disadvantage of the overall structural strength and stability.
