Framed+Structure

The heavy-timber system, the beams are strong enough to allow the upper story and roof to project beyond the plane of the ground-floor posts, increasing the space and weather protection. The members are usually exposed on the exterior. Modern light-frame structures usually gain strength from rigid panels (plywood and other plywood-like composites such as OSB) used to form all or part of wall sections, but until recently carpenters employed various forms of diagonal bracing (called "wind braces") to stabilize walls.

Timber Framing It uses fewer and larger wooden members. Timber framing uses mortice and tenon.

Conventional Framing It uses many timbers with smaller dimensions. Framing members are joined using nails.

Advantages •	 Easy and fast construction. •	 The timber frame can give the home owner the ability to make a creative statement through the use of design and specialty touches. •	Green •	Good climate and sound insolator Disadvantages •	 Because the structure is made from wood, it inherits any disadvantages wood may have. •	 Older timber frame buildings, built before the 1950s, are vulnerable to damage during an earthquake.

•	Balloon framing is a method of wood construction. It utilizes long continuous framing members (studs) that run from sill plate to eave line with intermediate floor structures nailed to them, with the heights of window sills, headers and next floor height marked out on the studs with a storey pole.

Disadvantages •	When a fire occurs, it travels very quikly from floor to floor. •	There is no platform to reach and construct the last floor. •	The workers will need very long members.

Platform Framing: Structure sits atop a concrete or treated wood foundation. A sill-plate is anchored usually with "J" bolts to the foundation wall. The floor is made of joist and in top of them, we find the walls, beams or posts.

It’s a simple method. This framing uses very thin members of wood.

Steel framing, This method is very similar to platform framing but, it’s much easier because of strength and rigidity of steel.

•	The posts and beams are fused using welding. •	 Since structural steel must be protected from corrosion, the skeleton is either covered by curtain walls or surfaced in concrete or, more rarely, painted.

Advantages •	 Fewer members are needed in this method. •	 This system is very resistent to earthquakes.
