Generally, a moment distribution method consists of the following steps:
1. Establish internal moment convention
2. Determination of member stiffness, k
3. Determination of moment distribution factor, DF from one end of member to the opposite
4. Determination of FEM
5. Distribution of moment applied on one node to adjacent members
6. Carry over the moment from one end of member to another end
