    Beam Reinforcement Calculation

    @human909 enough with your first moment of area Q=0 at the centroid diatribe. That may be so, but the typical Q of interest when calculating shear flow is the static moment of area of an area about a reference axis that is not its centroid. It’s right there in the Wikipedia article that you just...

    Digital Seal and Signature

    Well yes, technically it's a violation of board rules, obviously. As for what are the ramifications of violating a board rule. Who knows? That would be up to the board. In general though, you do not want your name showing up in the newsletter. You might think it is only a slap on the wrist...

    Beam Reinforcement Calculation

    @BAretired , what about the fact that, in this case of side plates positioned symmetrically about the neutral axis, the same total (not composite) resistance to bending could be obtained by installing through bolts or dowels through all three pieces at the the common neutral axis, or for that...

    Beam Reinforcement Calculation

    @lexpatrie , you really need to read the rest of the thread. You are missing the point. All the points you are making have already been made, but they do not satisfactorily resolve the the ongoing debate.

    Digital Seal and Signature

    Yes, but this doesn't meet the requirements of many state boards for a secure digital signature. I have had the exact same problem as @LOTE with AHJ's basically refusing to accept a pdf with a compliant digital signature because they couldn't put their silly stamp on the drawings. As if their...

    Shed Dormer on House w/ Exist Gable Dormer

    If you do either of these, make sure you either provide bracing for the compression edge of the "ridge" beam, or design for no bracing, which will probably result in taking a hefty bending strength reduction due to the beam "in"stability factor. If you are using multi-ply LVL the hit you will...

    Second Layer Reroof Less than 3 psf Procedure

    @lexpatrie What in the world are you getting at with this? It just seems like much ado about nothing to me. Maybe it's just me.

    Do you guys defer steel connections? Should it be on the contact?

    This is an interesting approach as an EOR. I'm curious how this arrangement is structured contractually. Do you provide the shop drawings under a separate contract with the GC or architect, or is it part of your basic design contract with the architect? Do you deliver the shop drawings as a...

    Second Layer Reroof Less than 3 psf Procedure

    Well it certainly doesn't mean this. Although you could certainly do this if you want, but expect it to potentially expand the scope of the problem far beyond determining whether the reroof exceeds 3 psf. I would say that what is actually required will depend on the local building authority...

    Shed Dormer on House w/ Exist Gable Dormer

    Well, I assume in the current configuration (i.e., before making the renovation you are currently considering) the point load at the ridge from the front dormer is resisted (i.e., "propped up") by the conventional rafters on the back slope of the roof which I assume are tied at the tails by...

    Deck & gabion wall foundation on helical piers & frost heave

    I have asked myself the same question in the past, and I have settled on 12 psf of plan area. There is basis for 12 psf lateral load in ASCE 7 lateral loads specified for reviewing stands, grandstands, and bleachers, and there is also basis for 12 psf as an upper bound for decks based on...

    Cracking in Wood Joists

    @Matt PE Just to reiterate, look again at your photo that shows the end grain of the joist on the left side of the photo. The radial crack that is inclined at an angle relative to the x-axis of the cross section and is also perfectly aligned with the pith at the center of the heartwood is...

    Cracking in Wood Joists

    I think those cracks are due to drying shrinkage of the sawn lumber. Basically they are checks. In photo "20250626_162427.jpg" you can see the end grain of the lumber and you can see that the crack is in the radial direction (perpendicular to the growth rings) and perfectly aligned with the...

    Steel-to-Steel Fastening with total thickness greater than 1/2"

    Standard procedure would be bolting or welding for structural steel applications.

    How do you brace home on addition project following the IRC?

    @XR250 is telling the truth. 90% of the time, I doubt anyone gives much thought to the overall lateral force resisting system when dealing with residential additions, other than to assume that the side that gets tied into the existing structure is automatically braced by the existing...
