Approx strength of wood vs.
Floor strength 2x6 vs oak.
Note that there are several ash species and they are not all the same strength.
By sistering up the 2 oc 2x6 with 2x6 s i would think the the strength of the floor would change to 2x6 1 oc.
Unlike syp oak is typically cut with a band saw rather than a planer.
An inaccessible attic space on the other hand might have a live load of only 20 psf.
Dense select structural select structural non dense select struc no.
To compare to other design loads residential floors are generally 40psf live and 10 psf dead decks and balconies are 60 or 100psf depending on area and 10psf dead load.
The span of a beam is dependent on a few variables.
Bur oak in the white oak lumber group is 10 300 psi.
In the trailer industry oak decking is referred to as rough oak for a reason.

Here is the strength of the woods in question.

I am not an engineer just my thoughts.

One way that i have seen an engineer fix a cut floor truss was to gusset on both sides with 1 2 plywood.
Strength in bending mor of white oak at 12 percent moisture content mc is 15 200 psi.
Oak is one of the only decking materials recommended for use with tracked equipment such as skid steer loaders and excavators.
Fewer posts on upper level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans.
Resistance may be measured in several ways.
The species of lumber size of lumber and the load it carries.
3100 2930 2700 2010 1900 1720 1670 1440 1320 865.
1500 1400 1200 950 900 800 775 725 675 425.
Acacia 17 500 psi.
660 565 480.
Ash 15 000 psi.
Another approach is to measure the deformation or strain that results from a given level of stress before the point of total failure.
The greater the resistance the stronger the material.
Hi all i have a project where i want to replace some plywood with some aluminum plate.
Andiroba 15 620 psi.
Strength may be defined as the ability to resist applied stress.
Amendoim ybarro 16 900 psi.
Rough oak is used for trailer decking primarily for its strength.
First floor live loads have higher requirements than second floor live loads 40 pounds per square foot vs.
Maximum floor joist span no.
One is the maximum stress that the material can endure before failure occurs.
