Moment Distribution Method (MDM), invented by Hardy Cross, is extremely powerful in it's simplicity and has been used extensively since it was first published by the ASCE journal in 1930. Part of its simplicity lies in the way that the bending moment diagram can be drawn graphically using superposition without needing to calculate the discontinuity equations for each segment. Complex structures can be solved relatively easily compared with other methods such as FEM, the Virtual.
