Framed+Structure+Presentation

- Framed structures are the skeletons of residential and commercial buildings across North America

Types of framed structures:

- Heavy timber frame: Strong enough to allow bigger spans (better weather protection) and those members are usually exposed on the exterior. __ Timber framing: __ frames structures of heavy timber jointed together with **pegged** mortise · Easy and fast construction. Good climate and sound insulator

- Light frame construction: gain strength from rigid panels (plywood) used to form the walls

__ Balloon frame: __ Method of wood construction that uses long continuous framing members (**studs**) that run from **sill plate** to **eave line** with intermediate floor structures nailed to them. · Easy to build up, and it improved the USA home construction methods. · It has the disadvantage that is very sensitive to fire and it travels easily and fast along good. __ Platform framing __ : Structure sits atop a concrete or treated wood foundation. The floor is made of **joist** and in top of them we find the walls, beams or posts. · Simple method · Uses thin and light member of wood // Differences // : · In balloon framing the studs extend from the base of the house all the way to the end rafter. · In platform framing each floor is independent from the other. __ Steel framing __ : similar to platform framing but, it’s much easier because of strength and rigidity of steel. · Post and beams fused together · Fewer members are needed
