## E min and `Never’

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. …

## Dimension versus Dimensional

I design structures. I am an engineer. In this day and age we design buildings so that they don’t fail; don’t fall down, and, in a sense, just barely don’t fall down. Seldom do we `overbuild’. And as such, it’s …

## Board Foot Measure (BFM)

We had a windstorm recently … some big trees down. After cutting up most of the fallen ones on my property (taking a couple weeks), I started in on one of my neighbor’s. One of `em is a big oak. …

## Code Based Conventional Roof Framing (SST Course)

I recently viewed a Course on the Simpson Strong-Tie Learning website titled `Code Requirements for Conventionally Framed Roofs. Good stuff! Kudos to Randy (`Author’). Per the Course, `Conventional Framed … ‘ means `Prescriptive’ framing, or, framing that does not require …

## `a constantly debated topic’ (pole barn versus post frame)

Pole barn versus post frame … how to keep the structure from flopping over? Consider a barn, or perhaps a shop, made using timber and `posts’. There are two main ways to keep it from flopping over. One way is …

## E min

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 …

## Accuracy of Deflection Calcs (and Eee)

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 (Apparent Modulus of Elasticity)

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 …

## roof rafter calcs … BENDING STRESS

Designing a roof rafter … (bending stress) … Linda wants a barn-shelter for her goats. Okay – I’ll do it. `Twelve by twenty-four.’ `Let’s go walk the site. It’s got some slope. I’ll make a stepped-barn, each section will be …
