I Beam Roof Construction

In homes you ll find beams in walls floors ceilings roofs decks and garages.

I beam roof construction. Here we have a wood framed gable roof. The design and structure of the i beam makes it uniquely capable of handling a variety of loads. Construction beams are horizontal weight bearing supports that bridge an area. Steel beams are widely used throughout the construction industry when supporting heavy loads is required commonly termed an i beam because of its shape beams provide great load bearing support when used horizontally or standing as columns.

A steel i beam costs 6 to 18 per foot for just the materials. Continuing on from part 3. You can also use the wood beam calculator from the american wood council website to determine maximum rafter and joist lengths. Steel i beams are pretty husky structural components used sparingly on a residential building site because wood is the primary structural material found in most homes.

Plywood i beams are strong and used to support floors and roofs in homes and other building projects. The image below shows a cross section of our simple 12 x 13 house from the joist span tables section of this tutorial. The i beam also called the h beam wide beam w beam universal beam ub and rolled steel joist is the shape of choice for structural steel builds.

Column beam construction use steel and wood. Instead a wood i joist roof system is framed with either a central bearing wall or a structural ridge a beam that carries the roof load to posts. The bottom half is carried by the exterior bearing walls. Their strength is derived from layers and grain patterns that run perpendicular to each other creating split proof construction that can support weight that would collapse single post beams.

Along with posts and columns which are the beams vertical counterparts they support the structural integrity of all sorts of buildings. Beam installation basics be careful. Floor beam span tables of residential structural design we will now look at roof rafter and beam design. The load from the top half of the roof is carried by the bearing wall or structural ridge.
