    Quiz; Structural Plan Review

    I was thinking concentrated tension, uplift, till I read your question. Did you assume compression or did that come from them?

    Wood Structural Design Data, chapter 1 pages 39 and 40 discuss notching of heavy timber beams, it reads the same as the code referenced NDS. Basically the same notching rules as the IRC with the exception that 4x and wider cannot be notched on the tension face except at the ends .

    Masonry Chimneys

    I'm guessing your gut is really saying "anchorage", I see nothing that would preclude an unsupported 500' chimney. Anchorage is not required in B, but it would be a good idea... as would vertical reinforcement in the 4 corners hooked under the footing rebar.

    log homes

    Oh, and the reason for the log standard is to avoid the situation Builder Bob just quoted... "outside of IRC, engineer required". The intent of these standards is to lessen the frequency of "engineer required" for common situations, which in this case they tried to make common log home...

    log homes

    If you check sections 401 thru 403 in the log standard it kicks it back to prescriptive for the same conditions that are prescriptive in the IRC. The span tables and provisions in the NDS would be my first choice, I think you'd find basically the same info in the free WSDD at awc.org.

    Hip rafter to ridge beam brace - porch roof where ridge beam is actually a ledger?

    See if the graphic on this calc works for the situation; http://www.timbertoolbox.com/Calcs/irreghip.html Basically slap that picture against the house wall. Umm, let's see if I can make that pic appear here; For the hip trib load; Take the measure of the base line where the arrow is...

    Hip rafter to ridge beam brace - porch roof where ridge beam is actually a ledger?

    The connection of the hip to ledger should be strong enough to carry ~2/3 of the hip's tributary load. The hip is a beam with the load increasing uniformly towards the ledger.

    Introducing myself, over a year later.

    Thanks Mike, I've been curious for several years.

    Rafter thrust and I give up

    Several times, My own house, built when I was in my 20's, has no ties in the 2 story 14' wide section, and no ridgebeam. It has a 4/12 pitch, so for every pound of vertical load it produces 3 pounds of horizontal thrust... the flatter the pitch on a simple gable roof the higher the thrust. In...

    Rafter thrust and I give up

    For something like this the engineering from the lvl supplier has generally been acceptable. "I've been doing it this way for X years"... also known as a class action

    Pier foundations

    The 6' pier spacing in pier and curtain wall construction is limiting the piers in that perimeter wall to a 6' spacing. If there are piers under the floor for midspan floor support in either pier and curtain wall or conventional crawlspace those piers are limited by soil bearing conditions and...

    Rafter thrust control for flush beam

    This is not the way I would want to try to solve the issue but here's a stab. Figuring the uplift is a trig problem but it's late and my brain says do it the graphical way, by looking at the proportions of the triangle formed. The sides of which are; the top of the joist, the vertical distance...

    Rafter thrust control for flush beam

    The main problem with the VB brace is that when thrust is applied it would tend to lift the joists as they seperate from the beam unless there were something like a ledger or upside down hanger above the joists to keep the joists from rising. Used as simpson specifies the hanger is in the...

    2015 IRC Deck Codes Completed.

    While I seriously doubt I'll be working under the '15 and I'll be downright pithed if I'm still rendering unto under the '18 I just finished reading the full blog post and it looks like you all did good. I appreciate your work.

    Another Genius Framer and more rafter thrust problems

    There's where I was going, still need to provide a tie or thrust restraint of equivalent capacity to the heeljoint table. The ply solution can likely be verified with the awc connections calc... although there is some eccentricity in the connection now.

    2) you never know 3) What connection would you approve to the plate. How is the plate connected?

    Another Genius Framer and more rafter thrust problems

    Is there a ridgebeam? I'm curious, how would you all react if there were a subfloor on the CJ's and a 2x plate on that with the rafters nailed to that plate?

    Ridge Board to Hip Rafter(beam) Support

    The hips thrust, if the jacks are tied both ways, no vertical support is needed just as in a ridgeboard roof. if they are not tied then a post is needed, just as in a ridgebeam roof. If the perimeter top plates are designed as beams and if the corners are connected well that designed solution...

    Double top plate header?

    Probably a double 2x6? Is that the header or is the rim joist the header?

    What is Saturday like for You

    Been clearing a path 600' up the mountain behind the house to get a wireless signal from the peak 6 miles away. Finally dried up enough again to pull trees down without tearing things up. The next victim was a chestnut oak, notorious for bad form but this was not a bad tree. Also known as sill...

    Go to any jobsite, bar or breakroom and ask the same question and note the responses. He got one good response... better than average, this proves there is some good info on the net. Go to any jobsite, bar or breakroom, would I have access to you? One must be cautious, there is alot of garbage...

    Deck Lateral Load Research Results!

    I agree with a good bit of what you've said Glenn. I do have an observation that I've brought up within this group before. I know what the APA calls for, but back in the real world... Because T&G plywood doesn't cover 48", very often the rim is connected by some toenails to the sill, nails in...
