Loading conditions (detailed design)

Roof load

The weight of the roof.
Additional slab load
Any extra loads to be applied as a uniformly distributed load.

Design live load

Uniformly distributed live load across the entire slab. This should include any scaling factors.
Internal wall load
The weight of the internal walls. This will be multiplied by wall height and length (both to be entered later) for each rectangle and converted to a uniformly distributed load across the slab.
