Floor live load and dead load.

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. The dead load on a floor is determined by the materials used in the floor s construction. Where d is floor dead load. Dead loads are also known as permanent or static loads.

The roof is also a dead load. The might of the dead load or lack thereof often defines how much live load it can handle. Roof live load may be reduced by the following equation. L r l o r 1 r 2.

3 3 dead loads dead loads consist of the permanent construction material loads comprising the roof floor wall and foundation systems including claddings finishes and fixed equipment. For instance dead loads account for the non dynamic forces that place continuous and permanent force on a structure. They consist of the building and all of its fixed components both structural and non structural. Reinforced concrete creates the heaviest dead loads but also supports the most weight with its tremendous compressive strength.

Structural steel offers much less of a dead load and provides superior support for live loads in multi story buildings.

The values for dead loads in table 3 2 are for commonly used materials and constructions in light frame residential buildings. Building materials are not dead loads until constructed in permanent position.
