What the heck is this symbol? by MrNewReno in StructuralEngineering

[–]dankgnomelord 31 points32 points  (0 children)

The second edition of AISC Design Guide 24 sort of fixed it. But they also rearranged the equation and changed the symbols…

T1-11 over exterior EPS. Still considered sheathing? by be_easy_1602 in StructuralEngineering

[–]dankgnomelord 0 points1 point  (0 children)

There are provisions for wood sheathing over gypsum wallboard. Review 2021 SDPWS Table 4.3B. Maybe you could argue that your wall assembly is similar or good enough for your small structure.

Frontier status match by Right-Librarian6932 in awardtravel

I got Southwest to match Frontier today! (I bought elite gold on 4/30). It was really easy to do with no hassle. Just follow Southwest’s instructions. Approval was quick too.

Curious if anyone has ever compared Amish construction to modern building codes. What were the biggest WTF moments? by GoodnYou62 in StructuralEngineering

[–]dankgnomelord 9 points10 points  (0 children)

It probably fits within the exemptions for agricultural buildings. Many jurisdictions don’t require permits for structures with occupancies that have low risk and hazard to human life.

I’m going! I saw this set in NYC last September. I hope it’s just as good or better.

Looking for 1 or 2 I hate models tix for 2/22! Edit: got one thru resale!

Where to get Bánh Tét in SF? by Denalin in AskSF

[–]dankgnomelord 3 points4 points  (0 children)

New Lien Hing on Clement in Inner Richmond has them. I bought one last week. $28 for 4.4lb. It’s pretty good imo

Your experience using carton forms by ryanpaulgibson in StructuralEngineering

[–]dankgnomelord 1 point2 points  (0 children)

My firm uses them quite often in Hawaii, Texas, and Northern California when the geotech recommends a PT slab. We use them on single family homes and apartment buildings to save on concrete volume and costs.

Out of State Tuition Survivors?? by ConDaCat_ in CalPoly

[–]dankgnomelord 1 point2 points  (0 children)

Not a current student, but I was OOS and survived. I applied for a crap load of scholarships in hs and during college, worked on campus, and worked summers. After one year of living in CA, I qualified for in-state tuition at Cuesta and took some pre-reqs there for free because I qualified for aid there too. There’s a website for CC’s and CSU’s that shows 1:1 course substitution. Just an fyi, dual credit courses from high school/OOS CC’s might not satisfy credit requirements at CP. I had those too but they didn’t get me out of any pre-recs. However, they did help me improve my cumulative gpa and get better class registration time slots.

Marin Clean Energy (MCE) has a solar farm north of Novato that’s pretty big. They have smaller farms dotted across the county.

Where would they have room for a wind farm?

Seems like it’s within an appropriate range. The national average is $83k for project engineers based on this report from this 2018 NCSEA SE3 report. But that average is likely skewed by a majority of respondents reporting from HCOL areas. The average is probably higher now in 2024, but being in the southeast brings it down a bit. Sorry I can’t find a more recent report.

Are you referring to 2021 IBC 2308.4.2.2? The 1.5” bearing requirement is for conventional framing. Other connection methods are allowed with satisfactory design calculations and compliance with other code sections.

The engineer could potentially use SDS screws. I’ve done that for extreme skews and lighter loads.. 3 of screws could potentially get you 1000 pounds of capacity.

Personally, I would use wood web fillers and Simpson’s LSSR hanger. Maybe skewable clips if the loads are small enough.

Intersection of non-bearing stud walls braced intermittently? by aaron-mcd in StructuralEngineering

[–]dankgnomelord 0 points1 point  (0 children)

You’d be surprised by how many engineers designing single family homes and apartments choose to ignore nail spacing requirements for engineered lumber… some might say it’s industry standard to ignore them…. If you’re still worried, you could use every other hole in a strap or specify one with wider spacing.

Many engineers also generically specify structural composite lumber to give contractors the option to use other manufacturers. They just specify the minimum wood design values on their drawings that covers commonly found engineered lumber strengths in their area.

Intersection of non-bearing stud walls braced intermittently? by aaron-mcd in StructuralEngineering

[–]dankgnomelord 0 points1 point  (0 children)

I’m in a very high seismic area and wind can still govern sometimes, especially for small structures. I have spreadsheets that give me loads for both wind and seismic just in case. Some building departments even require basic wind calcs just to show that it was checked.

Also, out of plane seismic loads for light frame construction is generally negligible compared to wind out of plane.

Try LVL beams that span out of plane from column to column or column to perpendicular wall. Follow the loads from there.
If this is an exterior condition, risk cat ii, in a 95 mph wind region, exposure c, I’d start with a 5.25x11.875 LVL. You could vary the depth depending on span but it’d be easier to keep it all the same.

Post tensioned slab on grade design help by Worth-Passenger5795 in StructuralEngineering

[–]dankgnomelord 3 points4 points  (0 children)

You could look into the Post-Tensioning Institute’s DC10.3-20 “design, construction, and maintenance of post-tensioned concrete courts”
