Tension and compression elements on Space Frame

Hi Clemens,

Thank you for response.

I think it should be have joints there(The top of columns), let's see what's happened if make it, fixed connection.

Result: the web members adjacent to supports are compression and it's true, but except them, all members and columns are tension, it's false.

and if I remove that joints from there(Top of columns), like you said

Result: the web members adjacent to supports are tension and it's false, and all members except the columns are tension and it's false.

thank you for your time.
