For the most part live load and dead load values for floor and roof systems are considered distributed loads.

Floor live load and dead load.

The might of the dead load or lack thereof often defines how much live load it can handle. The dead load on a floor is determined by the materials used in the floor s construction.

Structural steel offers much less of a dead load and provides superior support for live loads in multi story buildings. L r l o r 1 r 2.

The total dead load plus the total live load make up the gravity load for any given structure. Roof live load may be reduced by the following equation.

Reinforced concrete creates the heaviest dead loads but also supports the most weight with its tremendous compressive strength.

Where d is floor dead load. Where l r shall not be less than 12 psf and not more than 20 psf. Building materials are not dead loads until constructed in permanent position. Dead loads are also known as permanent or static loads.

If there s wall board covered ceiling suspended from the underside of that floor the dead load increases to about 10 pounds per square foot. Live loads or imposed loads are temporary of short duration or a moving load.
