Re: 16' Garage Door Headers

Paul,

I run into no reason non to accept an engineered (LVL) (gluelam) or similar component, based on the manufacturer's spec. sheet for that beam. That's all I've seen over the past few years. It's well within my condolement zone.

Min&Max,

How did you lot find out my real proper name? Anal Retentive.

"using dimensional lumber (4 x ?, multiple 2 x ?, etc.) that aren't on the bridge tables of the IRC"

Get an Engineer for virtually $150.00.

Absolutely, positively, unequivically, NO!

MtLogCabin,

"A minimum 3" Ten 11.25" net header size is required for opening from 6ft to a maximum 18 ft. That would accept intendance of the wind and seismic shear loads. Correct?"

Does not country that header (six' to 18') tin can be "dimensional lumber"; only that the minimum net header size shall be 3" X ll.25".

Maximum length for a "dimensional lumber" header for roof and ceiling only; would crave 4-2X12s and be express to a 14' i" bridge (Tabular array R502.5(1); which would require a six" broad wall; provided the edifice width was not more than 20'.

Now if they put double doors in; they could use double 2"x10"s (maximum bridge 8' v"); with support in the heart of the 16' foot opening; and your going to demand every inch of that 20' building width. Requires braced walls to be minimum 16" wide each X iii = 48" should allow two 8' openings (barely).

MtLogCabin,

Thanks, I don't know that stuff; and then I have to either go by the codes or Engineered. Heck, at 65, I don't desire to know that stuff.

It's proficient to know that some of ya'll learn stuff beyond the requirements of just knowing the codes.

Re: xvi' Garage Door Headers

Brudgers,

"From my time behind the counter, information technology's probably a expert idea to spot cheque designs submitted past engineers besides."

I'thou afraid that every bit an Inspector; I'm not qualified; nor should I be expected to be qualified to judge Engineered Designs (signed and sealed) that execeed the codes. In that case, I am required to be able to read the Engineer's plans; in order to insure that the structure is per plans.

"The Braille method of plan review is non very reliable."

Every bit far as plans that are submitted that are within the "Design Criteria" of R301; I also don't consider using the code requirements, to review plans as "the bullheaded method"; and I believe my answer to the original question reflects that.

Would exist so kind as to prove me what part of my answer that was incorrect; or where I used the "Braile method of programme review"?

"A minimum 3" X 11.25" cyberspace header size is required for opening from 6ft to a maximum 18 ft. That would take care of the wind and seismic shear loads. Correct?"

Does not country that header (half dozen' to 18') can exist "dimensional lumber"; simply that the minimum internet header size shall be iii" Ten ll.25".

Maximum length for a "dimensional lumber" header for roof and ceiling just; would require iv-2X12s and be limited to a 14' 1" bridge (TABLE R502.5(i); which would require a 6" wide wall; provided the edifice width was not more than than 20'.

At present if they put double doors in; they could apply double 2"x10"south (maximum span 8' v"); with support in the centre of the xvi' foot opening; and your going to need every inch of that 20' building width. Requires braced walls to exist minimum xvi" wide each 10 three = 48" should let two 8' openings (barely)."

Cheers,

Uncle Bob
