Hi,
I am looking for maps of wind speed and ground snow from around the globe. UK, Canada, China, all the code maps.
If you can put a map as an attachment please do so in this thread. Any advice on best way to get the maps please post. Original format of PDF file will work the best.
What...
If the question arises certainly calcs to back it up would satisfy the building department.
I always like using Simpson SDS 1/4" lags. Great shear value, less impact on both the ledger and studs, no pre-drilling required, more likely to connect to the stud in the center with adequate edge...
download enercalc and run the calc... pick a section that resembles the pipe... S and I (section modulus and moment of intertia)

I would use #2 or better just because less imperfections and knots.
The spacing requirement I think is a stretch and I would just accomodate the request. Send the code official the calcs at 24 o.c. and ask he send you an update if he determines the amendment does or does not apply to IRC...
There are cases supporting both flexible and rigid... i.e. if walls are spaced close together to assume rigid and distribute based on stiffness.
A very common example being shearwalls spaced at 15' max should flexible or rigid be assumed?
This varies from engineer to engineer. Anyway, here...
Modular companies need to stop thinking about flexibility and get their construction suitable to adequately support a multi-story home.
Alot of fundamental problems with modular construction currently.

Your sheetrock in your house will crack (alot) and you will have a trampoline for a floor and a sagging floor if you stay 9" with a 20' span.
Best to hire a structural engineer.

msucog,
Thanks for the link.
I'm not 100% sure if there is a miscommunication between my client and the building dept or if the township is actually not accepting a sealed report for this inspection without SI certification.
The town is in Middlesex county.

msucog,
I agree with you that alot can be learned by hands on experience.
In NJ I thought the same as in GA, if you are qualified in the field then your stamp was enough to issue the report. I've been providing inspection reports for years and never a problem before.
I guess my remaining...
Cap4000,
It looks like a PE is "qualified" as a special inspector of specific field. However, it seems as if an application must be filed to get "certified".
A township asked for SI certifications for a particular job. The client asked me to do the inspections and I said I would and a sealed...
There is a special inspector license. I think anyone with a couple years of related experience can take a test online and become certified.
I thought a PE was considered qualified without this additional license.

Has the requirements for special inspections in NJ changed recently? Specifically, are PE's not considered certified to perform these inspections without additional certification? Residential and commercial structures including the concrete, steel, one pass welds, etc.
Thanks

I'm actually trying to get as much info. as possible on CS ground snow so if you don't mind posting what you find out much appreciated.

Floor joists bottom bearing on an interior beam is normal construction w/out blocking if not required from load above.
Racking of the joists may suggest a bigger problem... No perimeter nailing into exterior rim board would certainly be one but to be honest have never seen the rim board not...
Ok...

The truss was run 3 different ways.
#1) all 2x4 web and chords with additional 20 psf in open areas.
#2) all 2x4 web and chords w/out additional 20 psf
#3) all 2x4 webs and 2x6 top and bottom chords.
I wasn't sure what...
StructuralJoe,
If you want to post a sketch of the truss profile with dimensions I will run it for you with Mitek software with all the load cases used today.
You mentioned the roof once had clay tiles. It would be interesting to know when those clay tiles were removed...
BTW... from your...
