What is the primary purpose of using a moment distribution method in structural analysis?

Step 1: Understand that structures can be determinate or indeterminate. Indeterminate structures have more supports or members than necessary for stability.
Step 2: Recognize that analyzing indeterminate structures is more complex than determinate ones because they cannot be solved using simple equations.
Step 3: Learn that the moment distribution method is a technique used to analyze these complex structures.
Step 4: Know that the method involves calculating moments at joints and distributing them to achieve balance (equilibrium) in the structure.
Step 5: Realize that by using this method, engineers can determine the internal forces and moments in the structure, ensuring it can safely support loads.
