In a rigid frame structure, what happens if a joint connection becomes flexible over time?

35. In a rigid frame structure, what happens if a joint connection becomes flexible over time?

1. The structure becomes stronger
2. The structure becomes lighter
3. The structure becomes more stable
4. The structure experiences increased deflection and potential failure

Answer

The correct answer is: D) The structure experiences increased deflection and potential failure

Explanation

Because of the loss of stiffness at the joints, a flexible joint connection over time may cause greater deflection and even failure of the rigid frame structure.
