Checks and cautions
| Check | Value | Status |
|---|---|---|
| Strength σ/fy | 69% | passes |
| Deflection / (L/200) | 49% | passes |
| Rafter strength | 75% | passes |
| Post utilisation | 22% | passes |
| Utilisation | 88% | with a caution |
| Depth vs frost depth | ok | passes |
- Embedment, mmThe footing resists wind uplift at above 80 % utilisation, or it is shallower than the frost depth. The soil resistance in the calculation is an estimate — check the soil on site.Foundation Ø300 × 1 200: 0.085 m³ of concrete per post. Wind uplift on the front post ≈ 9.1 kN (with γ=1.5) vs ≈ 10.3 kN (concrete weight + soil friction, estimate) → 88%.
