All fair enough. I appreciate your input. I've been doing this for 20yrs and it's just now coming up so... I guess it's not that big a deal overall. Will just tell the client this is what I'm comfortable sealing. If they want something that will crack when the wind blows they can go find some...
Thanks for the reply. I feel like I've spent all morning reading the text that references these tables trying to grock the intent of the code and I can't find anything in the text that I'm missing that would square this. It seems like the code should list what assumptions have been made to allow...
Thanks for the input. We almost never use any of the prescriptive design tables in the IRC, and I had already told the client that 2x4's don't work in this situation but they brought up the the table in the code and wanted to know why that wasn't acceptable.
I was on my back foot a little since...
In the 2021 IRC, table R602.3(5) lists the maximum stud height and stud spacing for "bearing walls". I don't see (if it's listed) if there are any restrictions on what species of wood can be used, what type of veneer is on the wall, and possibly most importantly, if there are any restrictions on...
I am working on the design of a ADU (accessary dwelling unit) in the backyard of a main house.
They want to tear down the existing 1 story ADU superstructure (but leave the existing concrete slab on grade foundation) and build a new 2 story ADU wood framed structure on top.
The original ADU was...
@Aellc
It's true there are areas that are tricky. But in large part, if the house is fully sheathed in Austin (90mph wind speed, exposure B, no seismic to speak of), there is not much to worry about. I would never just say "Oh its sheathed" and be done with the house as a whole. I look for the...
Luckily in the Austin area, seismic is not an issue, and really, unless there are unusual circumstances, wind is not typically a major problem either.
My main problem is that the City of Austin Planning and Review Department has decided that engineered drawings MUST show "braced wall plans", of...
@msquared48,
Thanks for the reply. If you don't mind I looking that up it would be really helpful. I have stumbled through much of the code, and do not recall anywhere it saying what the max cantilevered distance of a shear diaphragm is (in this case, it would be the roof sheathing).
I'm...
I'll start with the question, for those who dont want to read through a whole story, then elaborate.
Does it say anywhere in the 2012 IRC that ALL exterior walls MUST be a part of a "braced wall line" as defined by Section R602.10 (IRC 2012 page 164)?
In Austin TX US, the city has just adopted...
