In the moment distribution method, how is the distribution factor (DF) for a structural member at a joint determined?
1
By multiplying the stiffness of the considered member at a joint with the total stiffness of all the members meeting at that joint
2
By dividing the total stiffness of all the members meeting at a joint by the stiffness of the considered member
3
By adding the stiffness of the considered member at a joint by the total stiffness of all the members meeting at that joint
4
By dividing the stiffness of the considered member at a joint by the total stiffness of all the members meeting at that joint
