ASSIGNING AREA LOADS

[koshimli059]

Hello,

Does anybody know how should I apply loads to an area that is defined as Membrane?

My doubt arises because as I said before I define the area section as Membrane and in the Assign Area Loads Menu, the option for assigning uniform load has 'Shell' in parenthesis. It makes me think it's supposed to be used with areas defined as Shell only.

Thank you in advance,

You instead use a shell area with almost zero membrane modifiers (eg 0.01) and apply the loads on that.
The deflections will be significant large but you can ignore them. The mdoel will run without arithmetic errors.

As Jason said, membrane has no out-of-plane stiffness unlike plate; hence simply make the bending resistance to Zero. If your structure is plane, set analysis to 2D to ignore other deformations. Below is for your future reference.
