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 …

The nice thing about a stiff beam is that it won’t sag much. The not-so-nice thing is that it won’t `give’. In new construction, wood framing more or less starts from the ground up; wood members are placed on top …

The modulus of elasticity (MOE, E) of wood is most commonly used in the calculation of deflections (sag) of wood beams. By `beams’ I include joists, rafters, girders, decking boards, any … wood used structurally to support loads across spans …

When we examine deflections of wood members (beams, joists, rafters, girders, etc.) we generally look at two kinds, actually three … the deflection due to the `live load’, e.g., people walking on a floor, wind on a wall, and so …

(c) Jeff R. Filler, Pell City, April 2023 In earlier posts we looked at the `main’, or `overall’, wind forces on a rather low, wide `shop’ (here and here), and on a relatively narrower and taller `house’ (here).  Specifically, we …

In our earlier posts we determined the horizontal and vertical components of wind load on a `shop’ (here). The horizontal force was/is 500 lb, as acting on an 8-ft wide `swath’ of shop, which is framed with wood trusses at …

Now let’s look at the wind loading on the shop eaves. We ignored them previously, as we were getting `big picture’ wind loads on the building as a whole … or at least an 8-ft `swath’ of building, as a …

(c) Jeff R. Filler, Pell City, April 2023 In previous examples (here and here) we looked at the horizontal and vertical wind forces on a `shop’. The shop is/was a `pretend’ structure in a real location, Latah County, Idaho. It …

In an earlier example (here) we looked at the total horizontal force acting on an 8-foot `swath’ of a shop building, the idea being that the shop is supported by trusses on posts at 8 foot (ft) on center (o.c.), …
