Lumber Design Values - Western Wood Products Association

Flat-use adjustments are provided for Beams & Stringers and Dimension Lumber and depth-effect adjustments are provided for Structural Decking. Fiber stress in bending values for the various grade classifications of Machine Stress-Rated (MSR) Lumber are based on the correlation of the modulus of rupture (MOR) to the modulus of elasticity (E).

Structural Beam Stress and Deflection for Non-Engineers

If you stack two standard wood 4" x 4" on top of each other you get an Area moment of inertia calculated = 100. Recalculating the stress and deflection I get: Stress applied = 260.925 psi and a deflection of .44278 inches. Low deflection and stress and all I needed was another 4 x 4. This should work good and the risk of failure is minimized

Wood Strength - Workshop Companion

To compare the strengths and specific gravities of common domestic and imported woods refer to the charts below in “Relative Wood Strengths.” Wood has several kinds of strength. For a rough general estimate of strength refer to the specific gravity or density of the wood. When you need more detailed information there are additional choices.

Deck Beam & Footing Size Calculator | Decks.com by Seven Trust

Steel Alternatives to Wood Beams. If you’re building a deck wood isn’t your only option for beams. Unlike wood steel beams are not susceptible to the elements and won’t warp over time. They make for a stronger straighter safer and smarter alternative to wood substructures and may be more economical in the long-run.

Wood Strengths - WoodWorkWeb

Strength of wood is often thought of in terms of bending strength. This is certainly a useful yardstick of strength but is by no means the only one. A number of other strength criteria are described below. Stress is the amount of force for a given unit of area. It is typically measured in pounds per square inch (psi).

Online Deck Load Calculators - Fine Homebuilding

Because the calculator goes beyond the limits of grade live load and dead load in the DCA 6 and IRC tables you can design decks that fall outside the table limits. For instance if you know the dead load of the deck will be less than the prescriptive 10 lb. then you can select 5 lb. or 7 lb. and eek out a longer span.

Deck Framing: How to Determine Deck Framing Lumber Sizes

This chart is for southern yellow pine (SYP) framing lumber and similar strength woods. The table gives the maximum distance between joist supports which include beams and the ledger board. For example if the joists are spaced 16 inches apart and are 12 feet long the logical choice is a 2-by-8 joist which can span up to 12 feet 10 inches at

How to calculate wood beam strength

Accurate calculations of wood beam strength are essential in construction. Underestimates will compromise the safety of the structure and overestimates will lead to unnecessarily high costs. Wood beam strength is expressed in units of volume and is known as the "section modulus.
