👉Here’s a detailed breakdown of the two truss designs shown:

🔹 Truss A
- Slope: 12/12 (steep pitch, symmetrical rise and run) 
- Span (L): Between 5 m and 8.5 m 
- Divisions: 
  - Top chord divided into L/4 + L/4 
  - Bottom chord divided into L/3 + L/3 
- Angles: 60°, 30°, 30° 
- Special Note: Internal angles include 20° and 30°, giving a more distributed load path. 
- Structural Behavior: This layout balances forces with smaller internal angles, making it efficient for moderate spans.

🔹 Truss B
- Slope: 12/12 (same as Truss A) 
- Span (L): Between 5 m and 8.5 m 
- Divisions: 
  - Top chord divided into L/4 + L/4 
  - Bottom chord divided into L/3 + L/3 
- Angles: 60°, 30°, 30° 
- Special Note: Internal angles include 20° and 90°, creating a vertical member. 
- Structural Behavior: The vertical angle (90°) provides stronger vertical support, useful for central load transfer, but may increase material usage compared to Truss A.

⚖️ Comparison
- Both trusses share the same slope and span range. 
- Truss A distributes forces diagonally with smaller angles → lighter, efficient design. 
- Truss B introduces a vertical member → stronger central support, but heavier. 
- Choice depends on load type: 
  - Truss A: Better for uniform roof loads. 
  - Truss B: Better for concentrated loads at mid-span.

👉Steel Structure Roof Trusses Design Details

🚧Important question And answer For Construction Engineering Student

1. What is a steel roof truss?

Answer: A steel roof truss is a triangular framework made of steel members used to support roofs over large spans.

2. Why are trusses used in steel structures?

Answer: They efficiently carry loads over long spans with less material, making construction economical and strong.

3. What are the main components of a roof truss?

Answer: Top chord, bottom chord, web members, joints, and connections (bolts/welds).

4. What shapes are commonly used in steel trusses?

Answer: Triangular, Pratt, Warren, Howe, and Fink trusses.

5. What is the function of web members?

Answer: They transfer loads between top and bottom chords and maintain structural stability.

6. What materials are used in steel trusses?

Answer: Structural steel sections like angles, channels, tubes, and I-beams.

7. Where are steel roof trusses commonly used?

Answer: Factories, warehouses, stadiums, railway sheds, and large industrial buildings.

8. What are the advantages of steel trusses?

Answer:High strength, long span capability, lightweight, quick installation, and durability.

9. What are the types of loads acting on a roof truss?

Answer: Dead load, live load, wind load, and sometimes snow load.

10. How are steel truss members connected?

Answer: They are connected using bolts, rivets, or welding at joints.

👉Roof Truss Types

🚧Steel vs Wooden

💫Steel Truss Roof: A steel truss roof is made with steel members connected by bolts and gusset plates.

⭐️It is strong, durable, fire-resistant, and suitable for large-span buildings like factories and warehouses.

💫Wooden Truss Roof:
A wooden truss roof is made from timber sections joined together to support roof loads.

🔰It is lightweight, economical, and commonly used in residential houses and small buildings.

🎲Main Difference:

⏺Steel truss → stronger and long-lasting

⏺Wooden truss → cheaper and easier to construct
