Morning all,
I am currently running two models which are to represent a simple frame structure. In the first model, I use two beam elements which have a common node. Each free end I have restrained in all 6DOF and the joint node is restricted in 3, Z Translation. I am using the default coordinate system. For each beam, they have the same rectangular cross section and this is input using the beam properties area. I apply a XY load to the joint node and run the analysis. When I get the results of this, I get reactions at each of the fully fixed nodes, and bending moments in each of the members in plane 1 only.
The second model is similar however instead of rectanular sections, has L Sections. When I run the analysis, as before I get bending moments in plane 1, but now also in plane 2.
Am I now getting BM in Plane 2 as the sections are non-symmetrical? Also if I am using the default coordinate system, how do I tell what is Plane 1 and Plane 2?
Any help would be greatly appreciated!
Many thanks,
Rich
