Question

Which one of the following conditions, both elastic and plastic methods of analysis of indeterminate structures have to satisfy?
1. Yield conditions
2. Mechanism condition
3. Equilibrium
4. Compatibility of deformation

Answer 1

Correct Answer - Option 3 : Equilibrium

Concept:

In plastic analysis the strength of structures is used beyond elastic limit.

Conditions to be satisfied in elastic analysis of in-determinate structures:

1. Yield condition 2. Equilibrium condition

Conditions to be satisfied in plastic analysis of in-determinate structures:

1. Mechanism condition
2. Equilibrium condition
