Floor Framing System Lesson

Framing must transfer all gravity uplift and lateral loads to the foundation.

Floor framing system lesson.

Before you begin cutting or measuring grab a pencil and paper and sketch an outline of your floor. Foundation walls through connection of floor systems to foundations. In buildings including residential structures framing systems typically consist of the roof structure that supports the roof. Of the floor system directly above.

Within the context of simple engineering approaches that are familiar to designers system based design principles are addressed in this chapter. Length of span load to be supported specie and grade of lumber distance the joists are spaced apart. Framing walls are an alternative to mass walls which are made by. Floor framing floor framing consists specifically of the posts girders joists and subfloor.

Draw up a basic floor framing plan. Most raised floors in domestic buildings use plywood or particleboard sheets as structural flooring supported by a frame of timber joists. Therefore the issue of system performance is most pronounced in the above grade assemblies of light frame homes. Choose systems with simple floor and roof framing that are fabricated mostly on site such as sitecast concrete using any slab system without beams or ribs pages 107 123 light gauge steel framing pages 88 91 platform frame pages 49 65 masonry construction with either concrete slab or wood light floor framing pages 71 85.

The dead load on a floor is determined by the materials used in the floor s construction. Occasionally steel framing is used for the bearers and joists but the same structural principles apply. Openings in the floor require double joists beams either wood or metal horizontal. They are also easy to.

Extremely long spans staircases or interior walls typically require additional support which can complicate your framing. How to install metal studs. The dead load is the weight of the material used for the floor unit itself. The live load is the weight created by people furniture appliances and so forth.

When these are assembled. A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot. 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. Steel framing is used in most office and commercial construction and it has several advantages over wood.

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. In this lesson we looked at framing systems which are the structures of the building holding up the walls floors and roof. Deck exterior and interior load bearing walls beams girders posts and floor framing. 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.
