Problem
In RAM Steel Column, at a beam-column joint, the moment at the end of the beam doesn't match with the moment transferred to the column.
Explanation
In Ram Steel Column, the unbalanced moments are split between the column above and the column below, that is, part of the moment from the beam goes to the column above the joint and part of it goes to the column below the joint. The split is generally inversely proportional to the column lengths columns above and below the joint. However, if the column above and below have different shapes, materials, or orientation, the whole unbalanced moment will be applied to the column below the joint. More information can be found on this topic in section 3.4.4 in RAM Steel Column Manual.
