`Corners’
(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 …
Wind Load on Shop Eaves – ASCE 7-22 – Envelope Procedure – MWFRS
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 …

Cantilever Post Deflection (Post and Bracket)
Let’s look at a post, say in a shop, or a barn, acting as a vertical cantilever. This means that the base of the post is held rigid (not allowed to rotate), while a lateral (horizontal, or sideways) load is …
Wind Load on a Shop Using ASCE 7-22 (Envelope Procedure) – Part 2 (Horizontal Force)
Continuing from Part 1 … Step 6: Determine the external pressure coefficients, GCpf … Section 28.3.2. For Case 1 we get … roof slope tan-1 4/12 = 18.4° … interpolating between 5° and 20° … interp GCpf per slope, …

Wind Load on a Shop Using ASCE 7-22 (Envelope Procedure) (Part 1 – Velocity Pressure)
Part 1 – Velocity Pressure Let’s consider a shop to be constructed in, say, Latah County, Idaho, near the recently publicized college town of Moscow. The shop will not be a `business’, per se; in other words, people will not …

`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 …

Rafter Bearing and Anchorage
Rafter Bearing and Anchorage … So, of course, the rafters need to `bear’ on (be supported by) something. For Linda’s Goat Barn the rafters will rest on `headers’. The design of the barn, remember, is `pole barn’, e.g., rafters supported …
… and now for the headers
As an engineer I tend to design structures from the top down. First the roof loads, which determine rafters, or trusses, or whatever roof framing members. Then the beams/headers/girders supporting the rafters, then the columns or walls supporting the headers, …
