Rafter Thrust Design Guide
| Roof Type | Typical Thrust (kN) | Typical Pitch (degrees) |
|---|---|---|
| Residential Low-Pitch | 5–20 | 10–25 |
| Residential Standard | 20–50 | 25–40 |
| Commercial Steep | 50–100 | 40–50 |
| Industrial Heavy | 100–200 | 20–40 |
Note: Results are theoretical based on ASCE 7-22 principles. Actual thrust depends on roof design and load conditions. Consult a structural engineer for precise analysis.
