- TL;DR Summary
- Convention for horizontal beams seems to be void for bending moments when a member is completely vertical.
Hello:
I was looking for a widespread convention (akin to Hibbeler's, Beer's, etc) that deals with the sign convention of a vertical bar for bending moments.
For example, without knowing in advance, how do I draw the bending moment at a cut passing through point E in the figure attached?
Beam sign convention requires that it should be in such a way that it bends with an upward concavity an element containing that point. That doesn't seem to be possible when the member is vertical.Also, now that we're talking about conventions. Are there any conventions in 3D?
