Occasionally steel framing is used for the bearers and joists but the same structural principles apply.
Floor framing system lesson.
Draw up a basic floor framing plan.
Floor framing floor framing consists specifically of the posts girders joists and subfloor.
In this lesson we looked at framing systems which are the structures of the building holding up the walls floors and roof.
Steel studs are perfectly straight and they don t shrink split rot or mold.
Foundation walls through connection of floor systems to foundations.
Openings in the floor require double joists beams either wood or metal horizontal.
How to install metal studs.
Before you begin cutting or measuring grab a pencil and paper and sketch an outline of your floor.
The live load is the weight created by people furniture appliances and so forth.
Your sketch should depict the floor s basic shape and layout complete with any additional features like alcoves nooks and staircases.
Extremely long spans staircases or interior walls typically require additional support which can complicate your framing.
Deck exterior and interior load bearing walls beams girders posts and floor framing.
Length of span load to be supported specie and grade of lumber distance the joists are spaced apart.
Therefore the issue of system performance is most pronounced in the above grade assemblies of light frame homes.
Framing must transfer all gravity uplift and lateral loads to the foundation.
Floor joists a 2 x 8 2 x10 or 2 x 12 spaced 12 16 or 24 on center o c providing the strength to the floor system o size requirements.
Of the floor system directly above.
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.
When these are assembled.
They are also easy to.
A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot.
In buildings including residential structures framing systems typically consist of the roof structure that supports the roof.
In ground floor construction the joists rest on bearers which in turn are supported by brick piers timber stumps or some other column or wall.
Shear walls or steel moment frames in homes.
Most raised floors in domestic buildings use plywood or particleboard sheets as structural flooring supported by a frame of timber joists.
The dead load is the weight of the material used for the floor unit itself.

Within the context of simple engineering approaches that are familiar to designers system based design principles are addressed in this chapter.
