Design Of Steel StructuresEasyStructural FastenersWelded Connections

Which of the following is NOT an advantage of welded connections?

Noiseless operation, clean neat joints

Connections are rigid

100% efficiency can be achieved

Negligible warping

Correct Answer:

D — Negligible warping

Explanation:

Explanation: The Non-Advantage of Welded Connections Welded connections offer several advantages, such as noiseless operation and clean, neat joints, which enhance the aesthetic and functional quality of structures. The rigid nature of welded connections ensures structural stability and resistance to dynamic forces or vibrations. With proper techniques and quality assurance, welded connections can achieve up to 100% efficiency, making them highly reliable in terms of load-bearing capacity.

Which of the following is NOT an advantage of pin connections in steel structural connections?

To eliminate the secondary stresses due to rigid connections, due to the flexibility of joints

Speed with which the structure can be erected

Pin connections can eliminate complete rigidity at a joint since a pin can permit rotation at the most in only one plane

To make the frames statically determinate

Correct Answer:

C — Pin connections can eliminate complete rigidity at a joint since a pin can permit rotation at the most in only one plane

Explanation:

Explanation: Pin connections (also known as simple or shear connections) are fundamental in structural engineering, particularly in steel structures. Their advantages lie in their simplicity and flexibility, as supported by the provided text on "Simple Frames." Option | Status | Reason
