Intermediate anchorage

[JaouadAutocad]

I wanna model a cable stucture with three columns as anchorages, that's ok, but I'm not sure that it corresponds to reality, when a koad is applied to one span, the slack from the other span should be pulled into the span where the load is applied through the intermediate anchorage (see the photo), when I tried with two cables I'm having the results but I doubt it's physically okey, especially the the effort on the intermediate node isn't the same as we consider it a part of the cable 1 or the cable 2. And when I try with a single cable, I'm having troubles pinning it to the column, and having an error message "the structure is disjoint". Any help? Thank you!

Thank you. Isn't that a slide link? I've two questions.
1) Couldn't be done by the option "rigid link" too? (using 7 and 4 as slave and master nodes?)
2) The contact is ponctual, why are Rx, Ry and Rz chosen to be compatible too? (Anyway, I tried to liberate them but it didn't seem to work)
Cheers.

Correct.

Yes, it could.

Because a cable element doesn't transfer bending or torsion.

That has been of a very valuable help for me, thank you.
