In an earlier post (here) we looked at the probability of occurrence of some wood products ending up out in the field … say, in buildings, having actual modulus of elasticity values equal to (as low as) the values used …

In an earlier post (here) we looked at the probability of occurrence of some wood products ending up out in the field … say, in buildings, having actual modulus of elasticity values equal to (as low as) the values used …

In a previous post (here), we determined the size glulam roof beam required to not deflect more than 1.00 inches (under design load). We arrived first at a size 6.75 in. x 27 in., but it was not quite sufficient. …

This will probably be my shortest post. … In the determination of wood beam stability (lateral torsional buckling) with respect to bending about the X-X axis, use Ey min (not Ex min). The context here is structural glued laminated timber …

I continue to be mesmerized by this thing called `E min’. E min is the `minimum modulus of elasticity’ used in stability calculations in wood engineering design. E min (hereafter just Emin) is based on `regular’ modulus of elasticity, E. …

Let’s look at a situation where, after construction, it is required that a certain roof beam experience a deflection of not more than 1.0 inches (in.). The deflection limitation comes about by a required clearance between the ceiling and some …

So, in another post we looked at `board feet’ (BF), or `board foot measure’ (BFM). Now we’ll look at BF for structural glued laminated timber (glulam), and MBF, or MBFM. From the earlier post, amount of lumber is often described …

I was doing some reading in AITC 119 Standard Specifications for Structural Glued Laminated Timbers of Hardwood Species, Section 4.1.6 … “ … modulus of elasticity, E, values herein are the average values … The modulus of elasticity of wood …

E min (c) Jeff R. Filler, Pell City, Alabama, 2022 But First, E apparent and E true `E min’ is calculated wood property used in the design of structural wood members (beams, columns, etc.). It is a derived property, derived …

In the example above (link) we calculated a deflection of 0.599 in. How accurate is this number? (I showed it to three significant figures … accurate to half a percent?) Leaving out, for now, the accuracy/precision of the other input, …

E app (`Eee app’, `Eee apparent’, Apparent Modulus of Elasticity) is a design property for wood construction. It comes from the Modulus of Elasticity of the wood (E, MOE, Young’s Modulus). It’s not a `true’, or `pure’ property, and it …
