In roof trusses, the most frequent used section isa)Two-angle sections...
Angle sections are more resistant towards buckling than plate sections. Connections between angles are simple, and fabricated with ease, whether they’re bolted or welded. Angles offer a wide range of variety as you can use them singly, back to back and star shaped.
It is quite possible for a truss to experience ever changing loading in terms of both magnitude and directions. Under any given loading condition, a set of truss members remain in compression while others remain in tension. For one loading condition, a group of truss members remain loaded in compression while for a different loading condition, a different set of truss members remain loaded in compression. Although plate members perform very efficiently in tension, but they perform poorly under compression as they buckle under insignificant load (reason: very small radius of gyration). So, in place of plate members angle section members are used which can significantly resist buckling in comparison to their plate counterparts. (reason: large radius of gyration). For the above two reasons, angle sections are used in steel trusses so that when applied load reverses its direction and causes the tension members turn into compression members, the new set of compresses members don’t fail by buckling and cause catastrophic failure of the structure.
Four angle sections are used in Compression members.

Roof Trusses and Section Types
Roof trusses are structural frameworks used to support the roof of a building. They are typically made up of individual components called sections, which are connected together to form a rigid structure. These sections are designed to carry the loads imposed by the roof and transfer them to the supporting walls or columns.
Types of Sections Used in Roof Trusses
There are various types of sections that can be used in roof trusses, but the most frequently used section is a two-angle section placed back to back. This section consists of two angles, typically made of steel, that are attached together back to back. The angles are usually connected by welding or bolting.
Advantages of Two-Angle Sections Placed Back to Back
The use of two-angle sections placed back to back in roof trusses offers several advantages:
1. Strength: The two-angle section provides high strength and stiffness, making it suitable for carrying the loads imposed by the roof. The back-to-back arrangement adds to the overall strength of the section.
2. Flexibility: Two-angle sections can be easily customized to fit the specific requirements of the roof truss design. They can be cut and welded together to form different lengths and shapes, allowing for flexibility in design.
3. Cost-effective: Two-angle sections are readily available and cost-effective compared to other types of sections. Their simple design and ease of fabrication make them a popular choice for roof truss construction.
4. Easy installation: The back-to-back arrangement of the two angles provides a flat surface for connection to other truss components, making installation easier and more efficient.
5. Load distribution: The back-to-back arrangement helps to distribute the loads evenly across the section, reducing stress concentrations and improving the overall load-carrying capacity of the truss.
Conclusion
In conclusion, the most frequently used section in roof trusses is a two-angle section placed back to back. This section offers several advantages, including high strength, flexibility, cost-effectiveness, easy installation, and improved load distribution. Its simple design and availability make it a popular choice in roof truss construction.
