I am running a static analysis on a trussed structure that lifts objects from the ground.  The structure has 4 guy-wires that anchor the top of the structure to the ground.  Using a "link" connector will cause the links to bear load when lifting, so I need to use a "spring" connector in extension only.  Does anyone know where to set the K-value for different sizes of cables being used?

I've attached a screen shot of my setup.
