Floor Live Load And Dead Load

In other words the weight is distributed or shared uniformly by the members in the floor or roof system.

Floor live load and dead load.

Reinforced concrete creates the heaviest dead loads but also supports the most weight with its tremendous compressive strength. The might of the dead load or lack thereof often defines how much live load it can handle. For instance dead loads account for the non dynamic forces that place continuous and permanent force on a structure. For the most part live load and dead load values for floor and roof systems are considered distributed loads.

Where l r shall not be less than 12 psf and not more than 20 psf. A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot.

The values for dead loads in table 3 2 are for commonly used materials and constructions in light frame residential buildings. 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. Roof live load may be reduced by the following equation. Roof live load reduction.

The roof is also a dead load. Building materials are not dead loads until constructed in permanent position. Live loads or imposed loads are temporary of short duration or a moving load. Structural steel offers much less of a dead load and provides superior support for live loads in multi story buildings.

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