Continuous Cable with Intermediate Cable Supports

Hi,

I am trying to model a continuous cable with 13 intermediate vertical cable supports as well as 2 horizontal supports at the ends. The results don't seem to be making sense, as the supports at the end are only showing the initial tension and no extra horizontal load from the applied vertical load.

there is a similar problem here: communities.bentley.com/.../102697

but it is not exactly the same.

Any guidance would be much appreciated.

Regards, Paul
