Formula
Design load = 1.35 × dead + 1.5 × live (Eurocode ULS)
Worked example
Using the values pre-filled in the calculator above:
- Occupancy: Office (2.5 kN/m²)
- Dead load = 5 kN/m²
- Floor area = 50 m²
the calculator returns:
- Live load: 2.5 kN/m²
- Unfactored total: 7.5 kN/m²
- Factored design load (1.35G + 1.5Q): 10.5 kN/m²
- Total live load on the area: 125 kN
