Option 2 : Equilibrium condition

The conditions to be satisfied for the plastic methods of analysis are as follow.

1. Equilibrium Condition: All the equilibrium conditions, i.e. summation of all the forces and moments should be equal to zero.

2. Mechanism Condition: the structure at collapse must be capable of deforming as a mechanism due to the formation of plastic hinges, i.e., the ultimate load is reached when a mechanism forms. this is also called the continuity condition.

3. Yield Condition: This is also called plastic moment condition. The bending moment at any section must not exceed the full plastic moment of the section (M ≤ M_p).

For both elastic and plastic design analysis, equilibrium condition should be satisfied.
