Assignment to tension-only beam elements

sed

Hello.
Is it possible to assign only tension to the beam element?
I want to assign it to the brace material of the file.

It seems to be working correctly as a tension-only member. Is the problem that you want to apply a balanced tension to it instead of the external force that you currently have?

If you have a known tensile force that remains constant even as the frame deforms, you could cut it in two and add a pair of opposing forces to the new ends. In that case, you don't even need the elements of the brace at all.

If you want a pre-tension so that as it deforms the frame, the tension reduces, I think you could also cut it in two but connect the ends with constraint equations that impose a fixed relative displacement. Another way is to use thermal stress. A 3rd and probably the easiest way is the *PRE-TENSION SECTION card.

Relieved.
Thanks you.

I will try your advice.
