Moment distribution method stiffness factor

Moment Distribution Method Stiffness Factor, For modern computer analysis, the stiffness method is more general and handles any structure, but moment distribution remains the At a joint, the distribution factor of a member is the ratio of the bending stiffness of the member to the sum of bending stiffness of all What is the difference between distribution factor and stiffness factor?
