The floor joists form a platform on which the walls rest.

The wall studs rest directly on the sill plate and each floor "hangs" from the studs.

Is used to stiffen the floor and spread the load over a broader area.

Are designed for light frame construction. They are often used in place of floor joists. They contain a top chord, a bottom chord, and a web.

Is affixed to the floor joists and provides the surface on which the underlayment for the final finished floor will rest.

Are required when the joists are parallel to the overhanging area.

A special type of concrete. It is a mixture of one part Portland cement and six parts sand.

Engineered Wood Products (EWPs)

Used a lot in new construction. They combine wood veneers and fibers with adhesives to form beams, headers, joists, and panels That have uniformly higher quality and strength.

Oriented Strand Board (OSB)

A product in which long strands of wood are mixed with resin, placed in layers, and pressed and cured.

Parallel Strand Lumber (PSL)

A product in which thin strands of wood are glued together under pressure.

Laminated Veneer Lumber (LVL)

A product in which veneers of wood are stacked in parallel and glued under pressure. First used for high strength aircraft parts.

Consist of 1x or 2x lumber that glued in stacks to the desired shape and size.

Used primarily for long span applications in floor and roof systems.

Post and Beam Construction

Uses posts, beams, and planks as framing members that are larger and spaced farther apart than conventional framing members.

Walls that do not support much weight. They provide for wide expanses of glass without the need for headers.

The beams are placed at right angles to the roof slope. The decking is laid from the ridge pole to the eaves line.

The beams follow the roof slope and decking runs parallel to the roof ridge.

The horizontal flanges at the top and bottom of the truss.

The framework between the chords.

A load-bearing wall. Needed to support the joists and effectively reduce the span.

The lowest member of the frame in a structure.

A method of sill construction used in platform framing. It consists of a plate called a sill and a header that is the same size as the floor joists.

A 2" x 6" plate used in a box sill.

Balloon Framing	The wall studs rest directly on the sill plate and each floor "hangs" from the studs.
Joists	Provide support for the floor.
Cross Bridging	Is used to stiffen the floor and spread the load over a broader area.
Floor Trusses	Are designed for light frame construction. They are often used in place of floor joists. They contain a top chord, a bottom chord, and a web.
Subfloor	Is affixed to the floor joists and provides the surface on which the underlayment for the final finished floor will rest.
Cantilevered Joists	Are required when the joists are parallel to the overhanging area.
Cement Mortar Mix	A special type of concrete. It is a mixture of one part Portland cement and six parts sand.
