There is no matching wall on the first floor.
2x4 load bearing floor.
The dead load on a floor is determined by the materials used in the floor s construction.
If the wall is load.
There are no planned changes to the load bearing wall on the first floor which runns down themiddle of thehousemade up of 2x4s 16 oc.
A load bearing stud wall is any of the exterior walls in a wood framed house or an interior partition that supports a distributed load joists or a point load beams.
The gc expressed concern that the wall was bearing a lot of weight and we should do something to strengthen it but the architect felt the standard 2x4 construction would be fine.
Shear walls or steel moment frames in homes with large windows or other large openings provide the strength to resist lateral loads.
Stand the 2x4 up and its cross sectional area is l times the width of the beam.
That s just 1 5 for dimensional lumber.
Therefore wooden houses can stay warm in winter and cool in summer.
Then 2x4s 4 high 16 centers are adequate.
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.
Is this a crazy idea or marginally reasonable.
The roof is pitched about 7 12 and the roof rafters are 2x6.
The integrity of the overall building depends not only upon the strength of these components but also.
As long as the wall you intend to remove is not load bearing you can take it down with little thought toward structural support of the ceiling above.
But for load bearing walls it s an entirely different story.
When it comes to load bearing capacity strength weight ratios and insulation wood generally scores in every respect.
A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot.
Due to its structure wood does not allow much conductivity which is why wooden doors are ideal for keeping hot summers and freezing winters at bay.
You d also have to have the attachments to the top plate of the walls adequate to support the weight of the floor.
The wall itself is composed of wood studs at 16 inches on center and is constructed in the same way as non load bearing interior partitions.
Deck exterior and interior load bearing walls beams girders posts and floor framing.
Non load bearing walls vs.
Load bearing walls.
This wall would fall under a load bearing wall design or cripple wall design in section 602 of the irc code book.
I can t imagine a garage layout that would have a span short enough to make with 2x4 s even sistered.
First you must determine if the wall is load bearing or not.
How about putting support bars between the roof rafters and the 2nd floor 2x4 joists to transfer some of the load to the stronger roof joists.
In a perfect world the studs would not bow or twist but if i designed the wall i would have added a horizontal 2x4 brace end to end at mid height.
The larger this cross sectional area the better the beam does at resisting the load.
This is not a load bearing wall however.
If you lay a 2x4 down the cross sectiontal area is the length of the beam l times the thickness of the beam.
