What information can be found in the 2x12 span chart?
The 2x12 span chart provides information on the maximum allowable span for a 2x12 lumber based on the load it will support.
How much does a 16 2x12 pressure treated floor joist weigh?
It depends on its moister content.
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.
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.
How to build a platform over a sharply sloped floor?
How much slope and how long of a run? For short distance, up to 12 feet, and 12 inches of drop, you cut a 2x12 at the right slope and use them for the floor joist. For longer runs or greater slope, Use 2x6 level and use 2x4 legs under them.
The actual size of a 2 x 12 floor joist is?
It will vary a bit depending on age of the building. Old rough sawn are 2x12, new ones are 1 1/2 by 11 1/2 with 1/8 inch variation either way on the width.
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.
How do you calculate the torque capacity of a 4by4by44 railing post secured perpendicularly to a 2by12 sleeper joist with 36 of the post above the decking floor?
To calculate the torque capacity of a 4x4x44 railing post secured perpendicularly to a 2x12 sleeper joist, you need to consider the moment arm created by the height of the post above the decking, which is 36 inches. The torque (T) can be calculated using the formula ( T = F \times d ), where ( F ) is the force applied (such as wind load) and ( d ) is the distance from the point of rotation to the line of action of the force, in this case, 36 inches. Additionally, you must account for the material properties of both the post and joist, including their allowable shear and bending stresses, to ensure the connection can withstand the applied torque without failure.
What is a double joist?
Two boards nailed together for strength. Over a door or window opening, two 2x12 with a piece of 1/2 inch plywood in between for a header.
How much weight per square foot will a standard wood framed floor hold?
The answer to this question depends upon several criteria: 1. The span of the floor framing members 2. The 'on center' spacing of the floor framing members 3. The nominal dimension of the floor framing members (2x12 etc.) 4. The grade and species of the wood 5. Size and location of any holes or notches in the framing members A typical residential floor designed for a 10 psf Dead Load, 40 psf Live Load and a deflection criteria of L/360 (mid span deflection limited to L in inches/360): 2x12 joists at 16" on center spacing, Spruce-Pine-Fir #2, will have an allowable max span of 17'-10". 2x12 joists at 16" on center spacing, Southern Pine #2, will have an allowable max span of 18'-10". 2x10 joists at 16" on center spacing, Spruce-Pine-Fir #2, will have an allowable max span of 15'-5". Random thoughts: Thinset ceramic tile with mortar will add about 10 psf dead laod. Location of very heavy objects can be critical when determining a floors capacity.
What size wood should be used for floor joists?
The size of wood used for floor joists typically ranges from 2x8 to 2x12 inches, depending on the span and load requirements of the floor.
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.
