Tubular sections form the most economical compression members because ...
Tubes are most suitable for small loads and lengths. These sections are usually provided for roof truss and bracings. They have high local buckling strength and torsional resistance. In case of wind forces, the tubes are subjected to less force than a flat member.

Tubular sections form the most economical compression members because ...
Tubular sections are the most economical compression members because they possess high local buckling strength, more torsional resistance, and are subjected to less wind force than any other section. Let's understand these points in detail:
High Local Buckling Strength:
- Tubular sections have a high resistance to local buckling due to their shape and cross-sectional area.
- The circular shape of the tube distributes the load uniformly over the entire section, resulting in a more efficient use of material.
- This feature makes them ideal for compression members, where the primary failure mode is local buckling.
More Torsional Resistance:
- Tubular sections have higher torsional resistance than other sections due to their shape.
- The circular shape of the tube resists twisting forces more effectively than other shapes, which results in more stability and stiffness.
- This feature makes them useful in applications where torsional loads are significant, such as in trusses or transmission towers.
Less Wind Force:
- Tubular sections are less susceptible to wind forces because of their shape and smaller surface area compared to other sections.
- The circular shape of the tube reduces the drag coefficient of the section, leading to less wind resistance.
- This feature makes them ideal for tall structures such as communication towers or wind turbines that are frequently exposed to high winds.
In conclusion, tubular sections are the most economical compression members due to their high local buckling strength, more torsional resistance, and less wind force. These features make them suitable for a wide range of applications in civil engineering, such as in buildings, bridges, towers, and other structures that require reliable and efficient compression members.
