Floors - Live Loads
Minimum uniformly distributed live loads:
| Use | Live Load | |
|---|---|---|
| (psf) | (N/m2) | |
| Attics, no storage with roof slope no steeper than 3 in 12 | 10 | 479 |
| Attics, limited storage | 20 | 958 |
| Balconies | 60 | 2873 |
| Decks | 40 | 1915 |
| Fire escapes | 40 | 1915 |
| Garages, passenger cars | 50 | 2394 |
| Sleeping rooms | 30 | 1436 |
| Stairs | 40 | 1915 |
- 1 psf (lbf/ft2) = 47.88 N/m2 (Pa)
How to Calculate Load in N?
If you have the mass in kg - the load in N can be calculated as
F = m g (1)
where
F = load (N)
m = mass (kg)
g = gravitational acceleration (9.81 m/s2)
Example - Calculate the Load from a 800 kg Pallet
The load from a pallet with mass 800 kg can be calculated as
F = (800 kg) (9.81 m/s2)
= 7848 N
= 7.8 kN
