A circular column section is generally not used in actual practice because A. It is uneconomical B. It cannot carry the load safely C. It is difficult to connect beams to the round sections D. All of the above

The correct answer is: D. All of the above

A circular column section is generally not used in actual practice because it is uneconomical, it cannot carry the load safely, and it is difficult to connect beams to the round sections.

• It is uneconomical because it requires more material than other shapes, such as a square or rectangular column.
• It cannot carry the load safely because it is not as strong as other shapes.
• It is difficult to connect beams to the round sections because the beams must be specially made to fit the round column.

In addition, circular columns are more difficult to inspect and repair than other shapes. This is because the corners of a square or rectangular column are easier to access than the curved surface of a circular column.

For these reasons, circular columns are not commonly used in construction.
