how far can trusses span
The maximum span of a truss depends on several factors, including its design, material, load requirements, and the building codes governing its use. Here are some general guidelines for common types of trusses:
-
Residential Trusses (Wooden):
- Roof Trusses: Typically span up to 60 feet (18.29 meters) for simple designs, but some engineered trusses can go up to 100 feet (30.48 meters) with specialized designs.
- Floor Trusses: Usually span up to 40 feet (12.19 meters), but can go longer with deeper members or additional support.
-
Commercial Trusses (Steel or Heavy Timber):
- Steel Trusses: Can span up to 300 feet (91.44 meters) or more for large structures like arenas or warehouses.
- Heavy Timber Trusses: Can span up to 100 feet (30.48 meters) or more, but are less common in modern construction.
-
Agricultural Trusses:
- Often span up to 80 feet (24.38 meters) or more, depending on the size of the building.
- Engineered Trusses:
- Advances in materials and engineering allow for trusses to span even greater distances, sometimes exceeding 300 feet (91.44 meters) for specialized structures.
For specific projects, it’s crucial to consult with a structural engineer or architect to determine the appropriate truss design and span based on the project’s requirements and local building codes.
