I am putting in a suite in the bottom floor of the house.. Beam Span Chart Table. The span of a beam is dependent on a few variables: The grade and species of lumber, size of lumber and the load it carries. 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. Beam span maximums are based on a maximum. A (3)2x10 Hem-Fir Beam can span 18'-0 without any load on it. This means that no joists or walls are bearing on the beam at all. If any joists or walls are bearing on the beam, it cannot span 18'-0. A (3)2x12 Hem-Fir Beam can span 21'-0 without any load on it. This means that no joists or walls are bearing on the beam at all
load-bearing header: 2x10 vs 2x12. We're replacing a 7-foot segment of a load-bearing wall with a doorway header. All the window and door headers on this floor are double 2x12s, bringing the wall down to door height, but this will be a doorway In beam-speak you say: this header must carry X-pounds per lineal foot. This translation is the key to any structural sizing problem. Armed with this information you can determine the minimum size, span or strength of the beam (credit julio). Engineered wood components are sized using span tables that match various spans to pounds per foot of beam Go wider, more snow load, more than a simple roof, or a wider roof span and you'll need 2 jacks--at least with a doubled 2x header. With the above conditions it says a 2-2x10 header will span 8'5. With 50 psf snow load the span drops to 7'3 and add 8' to the buildings width and you lose a foot of span--6'3

To shorten the span, install two additional posts to bring the centre distance to around a maximum of 10' (less if possible). So for this particular pergola we'd need to position posts at 5' in from the outside posts, giving the two 5' spaces and a 10' space in the middle
Take the example of a first-floor 3-foot 2-inch header in a two-story 26-foot-wide house with a center bearing wall. A single-ply 9-inch-tall box header is good for up to a 4-foot span, and a 15-inch-tall box header works for spans up to 5 feet.

These nine beam spans are for built-up beams made up of either 2X8, 2X10 or 2X12 dimensional lumber nailed together as either 3, 4, or 5 ply beams. For example a 3-ply 2X8 beam would use three 2X8s nailed together side by side Your roof might not bear on this wall the garage door is in, but if it does, the generall rule of thumb for opennings is to use a double 2x6 for up to six foot openning, 2x8 for 8', 2x10 for ten foot, etc. Also, how far can you span a 2x12 header? A double 2x12 beam can span 12 feet; a (2) 2x10 can span 10 feet and so on 2x10, 2x12, and so forth). Steel framing members are formed in a process called roll forming by passing sheet steel through a series of rollers to form the bends that make the shape, e.g. the web, flanges, and lips of a stud or C-shape. Because this process is done without heat (also called cold forming) the studs and joist How far can you span a 2x10 header? When supporting joists that span 12 feet with no overhang beyond the beam, a double ply beam can span in feet a value equal to its depth in inches. A double 2x12 beam can span 12 feet; a (2) 2x10 can span 10 feet and so on

In areas with mild climates, patio roofs are generally designed for loads of 30 psf (pounds per square foot). For heavy roofs or in areas with substantial snowfall or winds, call your local building department for code requirements. The tables below give maximum spans for rafters and beams You can do this using header joists, endnailed across the cut ends of the interrupted joists, to carry loads to the adjacent trimmer joists. Where the header has to span a space less than 4 feet wide, a single header end-nailed to the trimmer joists will do.

The 2000 International Building Code book contains two full pages of mind-numbing charts for calculating proper header sizes in different situations. Fig. B shows the maximum allowable spans for different size headers in just one situation. As you'd expect, the deeper the header, the longer the distance it can span For example, a 3-ply 2×6 can span a maximum distance from post to post of 7 feet 11 inches for joists that span 6 feet from beam to beam. As with other structural applications, wood species makes a difference when it comes to 2×6 beam span. Lumber such as redwood, red pine, spruce pine, and cedar have shorter spans

Now I'm designing my own. I need a way to figure the maximum span for 2x dimensional lumber. Pergola beam span questions. I have a 16' w x 12' deep concrete patio. I want to build a pergola over it. I will be using 6x6 posts (cemented in the ground), 2x8 or 2x10 headers or beams at 12' lengths, and rafters 2x6x18' laid on their 2 side with 2x2x12' slats on top. I built a pergola before which was 13' x13'
For a header to safely span 8 feet and support one floor, ceiling, and roof load above it, the recommended header size is two 2X10s with the plywood sandwich. (This second example is the example I assumed that Allen was referring to; although I agree assuming is dangerous.)Based on the 25% margin, this header would be adjusted to two 2X12s. Typical applications include door & window headers, floor beams, ridge beams, and hip and valley beams.

Maximum length for a dimensional lumber header for roof and ceiling only; would require 4-2X12s and be limited to a 14' 1 span (TABLE R502.5(1); which would require a 6 wide wall; provided the building width was. These beams or headers each have their own engineering formula, so calculations on these need to be done professionally. Another resource could be a Building Code book. Many codes have span tables that have pre-determined spans associated with the loads required for your area. These are most helpful for those simple header sizes usually under 6.
How to build a three-ply laminated 2x10 beam and what fasteners to use. by Patrick. (Long Island, NY) I am building a ground level deck (max 24 of the ground).

So we might go for that if I can find it in Austin, or built a true flitch beam with 2 2x10 and 1/2 steel plate Step 3. Design a beam depth based on the rule of thumb for estimating the depth of manufactured beams which is to divide the span by 20. Beam depths are typically 5 1/2 inches, 7 1/4 inches, 9 1/4 inches, 11 1/4 inches, 11 7/8 inches, 14 inches, 16 inches, 18 inches, and 20 inches. Advertisement. Christian Hollendonner

Beam Span Calculator Also, in one section of the deck I am designing, a 9' long 4x8 PT Dug Fir beam. I see a 7' joist span allows a maximum 7' beam span. Am I cutting it to close to A span of 12 feet would require 2x10's and spans between 14 and 18 feet would require 2x12's. Anything over 18 feet would require 4x4 or 6x6 posts mid span to cut the actual span in half. If you are thinking of building any bridge with a span greater than 20 feet, you better get a structural engineer involved, plain and simple Step 2: Cut and Attach Spacers. Cut pointed spacers from a sheet of 1/2-inch pressure-treated plywood (the points prevent rainwater from sitting on the plywood and soaking in). Fasten the spacers, points up, to two beam lengths with 1-1/4-inch screws. Attach the spacers at 16-inch intervals. Step 3: Clamp and Screw
