Question

Plastic analysis must satisfy the following conditions

• A. Mechanism condition
• B. Mechanism condition and equilibrium condition
• C. Mechanism condition, equilibrium condition, and plastic moment condition
• D. Equilibrium condition and plastic moment condition

Hint:

Remember, in plastic analysis, ensure that all three conditions (mechanism, equilibrium, and plastic moment) are met for the system to be analyzed accurately.

Answer 1

The Correct Option is C

Plastic analysis in structural design requires that the mechanism condition (allowing plastic hinges), equilibrium condition (for force balance), and plastic moment condition (ensuring plastic bending capacity) are satisfied for the system to be stable and collapse properly. Therefore, the correct answer is (3).
