Angle Section Compression Members: Valid Configurations

A compression member is a structural element designed primarily to resist axial compressive loads. Angle sections, which are L-shaped steel profiles, are frequently used to construct these members, often referred to as struts.

Types of Angle Section Struts

When using angle sections for compression members, several configurations are possible:

• Continuous Member: Angle sections can be arranged to form a continuous structural element, contributing to the overall stability and load-carrying capacity.
• Discontinuous Single Angle Strut: A single angle section can be employed as a strut. Its effectiveness depends on its length, end connections, and slenderness.
• Discontinuous Double Angle Strut: Two angle sections can be used together, either back-to-back or separated by packing materials, to form a more robust strut. This arrangement often provides better stability and load-carrying capacity compared to a single angle.

Since all the configurations listed (continuous, discontinuous single angle, and discontinuous double angle) are valid ways to use angle sections as compression members (struts), the option encompassing all these possibilities is the correct one.

Conclusion

Therefore, a compression member consisting of angle sections can be a continuous member, a discontinuous single angle strut, or a discontinuous double angle strut.
