    3/4" Tongue and groove pine as a thermal barrier over spray foam

    I've put up miles of it in ceilings over foam, R316.5.2

    What could be in store for me.

    At 1/2" dia and up anchor bolts are not required to be galvy... I believe this is still true? If the lateral load gets through your perimeter walls and the house is depending on those post connections, there are bigger issues on the horizon.

    Size, placement, And type. I was building the wife a plant stand yesterday using odds and ends, a few types of screws crossed my path. The primeguards had no approvals or astm numbers, I looked at my gun nails, an ESR #, the 16 common hand drives conformed to ASTM 1667. Then I was working with...

    Let's play whatever the inspector will accept...

    Well.. can I change my answer? A common rolled thread wood screw with a bending yield strength of 100,000 psi, the same steel called for in a nail, is the screw in the NDS. That's the soft bright, cuss the stripped head, screws (not a hardened, brittle, deck or drywall screw). A #9 has a root...

    Who needs calcs, its a materials problem. I think the engineer stated that framing screws were at least equivalent to the nails specified. Carry a structural screw out to the jobsite with the letter and hand it to the contractor, have him back out a deck screw and compare it to a structural...

    Detached garage/Upstairs apartment egress

    Protection as in from fire, you're allowed to run into it you just can't burn it. Full log below, watch your penetrations, you'll need to get the drains down in a drywall chase or something. Wall stiffeners on all but the stairwall, is it ok?

    Detached garage/Upstairs apartment egress

    It's no different than any other house with an attached garage, the protected stairs dump you outside or into an alcove that has a rated door into the garage and one to outside. A deck at one gable end provides another door out... Cantilevered attic trusses that rise from the fascia rather than...

    Iroquois Theater Fire

    I appreciate your posting that and have reposted the link on "another" forum. Similar well written articles would be much appreciated as you all come across them.

    Inspector/Building Official or Contractor/Tradesman

    Sure, all I ask is "cite?" I'm happy to have the inspector get out their book and look it up so we can discuss it together, some real misconceptions exist on both sides, the response tells me alot.

    Welcome to the forum 97Springer! Merry Christmas to all, I just step back and let Mom and my sisters decide on the main event, we're taking the apple pies and I'm not sure how many cookies she baked. Well, not sure how many will make it till then, still a little damaged from quality control...

    Shear Collapse or Vertical Failure

    No pics? :) Self employed, motel 6 :pitty I was looking for something on photobucket and remembered these. They are sort of related, there are some folks on another forum that are building on unbraced piers, I was trying to show the problem. Then there were all kinds of cobbled together...

    propane tank boom

    So the propane company is accepting liability in these cases when they have filled one of their tanks?

    Building Width?

    I've visualized the tributary area to the girder or header the table is assuming and describing. The table makes assumptions that may not be true in all cases, for instance joists and rafters may not be running in the same direction.

    propane tank boom

    That's 3 in about as many years within 100 mile radius of here. Locally bollards were checked or retrofitted after an unprotected tank killed the occupant of the car and destroyed a building... right in front of the fire dept. The next day I noticed the tank behind the local watering hole was...

    Structural redwood?

    No engineer needed for these, it is acceptable within it's published limits. It is stronger and has better shear resistance than SPF but is less stiff. Take a look at the design values for cedar, white pine, northern species, eastern hemlock, etc. I had one BO tell me that the only hardwood...

    Structural redwood?

    One more thought, give the rules writing grading agency for redwood a shout, there's a contact link on this page, I'm linking you to their publications page; Redwood Inspection Service

    Structural redwood?

    The code ref would be the supplement to the NDS, a free download on the awc.org site. No engineer needed, you can save the applicant a few bucks. The prohibition has been non code. The quick way is to hit their span calc... according to the NDS; Maximum Span Calculator for Joists & Rafters...

    4 x 4 #2 rafters, pine max span

    Continuing with #1... I do see a need on both sides of the counter for more understanding This is where I was stuck last night, its early on in writing the first section but I think it might be good to see my intentions. I would appreciate knowing if something along these lines would be...

    4 x 4 #2 rafters, pine max span

    When you picked which table to use you were engineering. I hope we are now agreed that the 12" table does work a bit closer to the situation at hand. That will not get the op out of the jam his client is in, it was just an opportunity to hopefully turn up the light. I think we've had 3 threads...

    4 x 4 #2 rafters, pine max span

    In the op the 4x4 rafters are on 2' centers. From my read of your original post (#2) it sounds like you are proposing using the 24" oc 2x4 table. In that post you roughly equated a 4x4 to a 2x4 and suggested ignoring the the additional thickness. The section modulus and the moment of inertia for...

    Deck Foundation Sizing Survey

    That's what has worried me in the past, not settlement but a slender poorly footed pier to grade on solid ground with loose fill around its' tube and an eccentric post placement at the hinge between pier and post. I try to talk clients into running the posts down to the footing to avoid that...

    Cantilevered Beam

    Hanging on ledgerlocks, lags, bolts... where are you seeing the minimum bearing being met in that? Which member of that beam is taking almost the entire load? The rail needs to be able to take 200 lbs in any direction, the infill pickets #50/sf. DCA6 is worth looking at.

    Cantilevered Beam

    I'm guessing the girder is hanging just on bolts at the post, figure 9 in DCA6 vs the approved figs 4&8

    4 x 4 #2 rafters, pine max span

    Mainly hoping to flesh this out, it is incorrect, If so the 12" oc table would be appropriate for 4x4's@24" oc, it is more than equivalent to 2-2x4's.
