What is the maximum span on a double 2x12 beam supporting 2x8 ceiling rafters and an acoustical ceiling?
Depends on the area above the ceiling joists. Is it a live load (living space) or dead load (just the joists with maybe an attic above)? Also, the length of the ceiling joists from the last bearing point is a factor. How much weight is bearing on the beam is the critical issue.
What is the maximum span of a 2x12?
The maximum span of a 2x12 lumber depends on several factors, including the wood species, load conditions, and whether it is used as a floor joist or beam. Generally, for standard residential applications with a uniform load, a 2x12 can span approximately 12 to 16 feet. However, it's crucial to consult local building codes and a structural engineer for specific requirements and safety considerations.
On a deck what would be the maximum spacing of 2'X12' floor joists on a 20ft span?
Even using a 2x12 the spacing for 20 feet will be less than 12 inches on center. I would recommend splitting the distance with a double beam perpendicular to the joist run. This will allow you to go up to 24 inches on center. Your span will only be ten feet aproximately this way. I would double the beam. (2-2x12 joined together) Good luck. when building your beam make sure the laps on the beam are at least 6 foot apart and put a good wood glue on the 2x12s plus for added strength put 1/2 inch O.S.B. in between the 2x12 and I would also lag or bolt them together, at about 16 to 24 inches O.S.B. = Oscilating Strand Board.
What size beam you need to support a 10 ft span load bearing wall?
Depends on how much weight is above it!! but on 1 -2 story wood framed structures triple 2x12's glued and nailed will do the trick
How far can a 2x12 span?
The maximum span for a 2x12 beam depends on various factors, including the type of wood, load conditions, and whether it's used for floor joists or beams. Generally, a 2x12 can span approximately 16 to 20 feet for residential floor joists, assuming a typical load of 40 pounds per square foot. For heavier loads or different wood types, it's crucial to consult local building codes or a structural engineer for precise calculations.

What is the maximum span on a double 2x12 beam supporting a 2nd floor load with no roof load?
About 5metres(16') but would have to be stress graded timber.
What is the max span on a double pine 2x12x22?
The maximum span for a double 2x12 beam made of pine can vary depending on factors such as load requirements, local building codes, and spacing of supports. Generally, for residential applications, a double 2x12 can span approximately 12 to 16 feet when used as a beam. However, it's crucial to consult local building codes and a structural engineer for specific requirements and load calculations.

What is the maximum span on a triple 2x12 beam supporting a roof?
Triple? That sounds an awful lot like gluelam... Which requires engineer approval to meet code. The inspecting engineer will be able to tell you.
You removed a load bearing wall they had reinforced the post and put in a beam 2 months later you are noticing cracks in the wall and a previous crack had lengthened what are my walls saying?
If I am reading the question correctly, a load bearing wall was removed and replaced with a beam? Clear span, no post in the middle? If cracks are appearing, the beam that was used was not big enough. For any space of 8 feet or more, 2x12 and plywood should be used for the beam or an engineered truss used.

What is the maximum allowable span for a double 2x10 beam in a structural application?
The maximum allowable span for a double 2x10 beam in a structural application is typically around 12-15 feet, depending on the specific load and building codes.

How do you make loading bearing beam out of 2x12?
Usually it is in a 2x4 wall. Take two 2x12's the right length and put a strip of 1/2 inch thick plywood between them. Nail through from each side at regular points alternating the spacing on each side. This ties everything together. The plywood and the different grains of the 2x12 give it more strength than the parts separately. good answer above. make sure to crown both 2x12's in the same direction and adding construction adhesive to plywood before nailing all together gives it even more strength. Install it with crowned side up naturally!
