As an example, create a concrete column with an L symmetric cross section (select the cross section type from the list of defined cross sections). On the top of the column create two beams with a rectangular R25*50 cross section.
Once created, the beam axes are crossing in the L cross section's center of gravity.
Actually, the beams are created at the top face of the column, which leads to an eccentric compression action. To correctly model this situation, proceed with the following steps:
