    Number of Jack Studs - gable wall

    You do the engineering. Depending on how much design flexibility you have you do less or more careful engineering. Myself, I would not direct the load to the top of a header. I would direct it to to the jack studs supporting the header. --- There are a lot of issues that redistribute "point"...

    Ceiling framing

    The lumber appears to be properly grade stamped. The construction does not appear to be prescriptive. I expect the proper engineering has been done.

    Joist hangars and drywall screws

    Table 12.3 G comes to mind. But that is only from "memory." But my point was (and is) that there are approved methods of showing that a fastener is proper. Any AHJ who asks for engineering should not accept a guy swinging a hammer. You either have the math or not.

    Joist hangars and drywall screws

    Same footnote (different values) for hardened nails. Same footnote (different values) for standard nails. Not surprising. "field demonstrations" are not useful in determining the suitability of either nails or screws. Anecdotal evidence is also not that helpful. --- Showing the suitability of...

    Joist hangars and drywall screws

    You can look up the strength of the screws in the NDS for Wood Construction and compare that to the of mails from the same document. --- It appears to not be legal for a manufacturer to approve only their own screws.

    Attic access

    You seem to have practiced engineering before. I don't see why my comments would induce you to not do engineering.

    Attic access

    I like that idea. Perhaps equally good is to nail and glue a 3/4x4x4 sheet of plywood over several truss cords and cut a hole for the proper sized openings. Most likely sufficient to allow the cutting of a truss.

    Floor Girder Problem?

    Did you notice that in post #24 Jar had the span wrong, the tributary "width" wrong, and the dead load wrong? You might notice that in post #32, Jar indicated that he would accept his own unsealed unlicensed opinion if BeamChk (improperly used - wrong span, wrong tributaqry "width", and wrong...

    Floor Girder Problem?

    You said you require an engineer's stamp. Show me the code section that requires an applicant to provide a stamp. ---- I am amazed that you admit you don't know how to enter data into Beam Check, but you accept the results you get from doing so.

    Floor Girder Problem?

    The "But" indicates it is not up to me to accept it or reject it. I am happy with a list of beams and loads and the word "OK" by each. That is all I ever show.

    Floor Girder Problem?

    As a "PE" I do not work for the AHJ. I provide information to my clients. That information is never stamped. My clients have the option of passing the information on to the AHJ if they desire. (Unless I am doing the actual physical construction the engineering is for "informational" purposes...

    Floor Girder Problem?

    One nice part of being an engineer is that you can write up a spread sheet to "do it your way."

    Builders Driving Me Insane 2009 Windbracing

    As I understand the facts: This is custom home with a buyer in hand. The house would have been code compliant if the permit was applied for a few days earlier. The problems were caused by a mistake at the AHJ's office. --- Get everyone to agree to build under the prior code.

    Floor Girder Problem?

    "Are you happy to accept that 4 plys will span the extra inches in the equation at hand?" (yes) I am happy to accept the engineering that DRP outlined. It is what I would do. (I did not read his post with any more care than to determine that his approach is the same as mine.)

    Floor Girder Problem?

    My post was to indicate that according to some sources the benefit of multiple plys seems to diminish quite quickly. And that 8" depth seems to be beyond the reach of multiple plys of 6". I am very happy to accept that the obvious engineering that says 3 plys will support 50% more load (plus...

    Floor Girder Problem?

    I agree with you. But tell me "Who is responsible when the inspector gives 'wrong" advice?" --- I did s search using "wood girder span tables" A responsible source gives the following allowable loads for girders spanning 8': 4x6 223 pounds/ft 6x6 237 2x8 412 It would appear that 6" of...

    Floor Girder Problem?

    Perhaps you can notch the ends. But it should be easy enough to use a thicker bottom plate. Nail 2 2x's together and drill the top one for the nut, bottom one for the bolt. --- Is this an inspection or your construction? Inspectors should not be offering solutions.

    Builders Driving Me Insane 2009 Windbracing

    "You need windbracing on all exterior walls. And the back wall of the structure....where are you installing the windbracing so that you don't exceed 25 feet without any windbracing and you have a wall of windows that spans around 40 feet without any form of windbracing." One problem with AHJs...

    booster fan in a chimney

    Since chimney fires are common, I thought I would look at the product referenced above. It appears the product does not sit in the chimney. It simply blows air into the chimney. Any fan in the chimney would draw my attention and concern.

    Brain Tease: Service Conductors

    It would be nice if the size of the service was specified. In my location the service conductors are sized by the electric company. I don't think you have a say in the matter.

    Making a door larger to accommodate a 6' slider

    Geodesic domes and the Rainbow Bridge in China. All nonprofessionals, most professionals, and many engineers cannot do an accurate assessment of designs they are not familiar with. --- The Rainbow Bridge, a bunch of short slender pieces of wood used to span long distances without any...

    Egress from "wine cellar" (R310)

    I think Robert Ellenberg's post (as well as my previous post) was that a basement has no habitable requirement. I don't remember the details of the basement v. crawl space discussion. I think I came away thinking there were no substantive differences.

    Making a door larger to accommodate a 6' slider

    Misstating my position is not the way to prevail. AHJs have authority to accept prescriptive code compliant issues and to accept engineering for non-prescriptive issues. Any and all non-prescriptive structural issues issues need to be dealt with by doing engineering. Comments like "That's just...

    Making a door larger to accommodate a 6' slider

    Yes, it does require engineering calculations. --- incognito and Pcinspector1 seem to understand the process.
