    Ray! That is truly how it's done.....I'd say your garage will withstand an f4 tornado. commerical builder here and I can't tell you how many framers scratch there heads when I ask where the shdu brackets are, you would think they would ask why so many 5/8" rods in the slab.....they just frame around em. Very nice video, air gap below bracket is key.

    hi ray, as a retired class a contractor and builder, i must commend you for the quality of the construction and subs. it don't come cheap. when i was in business, our motto was "do it right once". the cost of construction is soon forgotten long after the quality remains. congratulations on the good decisions you have made to get to this point in your life. it is admirable. i worked in the washington, d.c. area for 35 years. we made a ton of money by simply doing good honest work. enjoy, enjoy, enjoy....and worship your wife!!!

    I have them in the corners in the framing, saw them when I replaced the sheathing at the corner by the patio. We have hurricanes here not earthquakes. Have a lot of termite damage on 11' of garage overhead door wall and need to splice in new top plate. Brick face on front of house so can only get to framing from one side. Looking at different videos for pointers as only the sill plate in good shape. Direct on concrete so must be pressure treated.

I am running into an issue where I don't have enough bolt length to install the washer like you have and flipping the washer on its side would give me that additional inch or so to thread in the nut.

    Simpson also makes "strong ties" that are used in hurricane country. They are smaller, but more numerous, clips which hold the studs to the bottom plate and top plate, and the rafters/trusses to the top plate. I can tell you first hand they are not tornado proof. Anyway, I used them on homes in FL (required) and in TX (not required). As far as earthquakes, we are clueless around here.

  • @terrygoyan
    @terrygoyan 7 лет назад

    I noticed only one thing different that would be required under current California code. On the long wall run your HD's are located maybe 8 or 10 feet apart with 2 by studs between. Where I build, code requires 3 by materials at the edges of the shear ply, or OSB as the case may be. This prevents the studs in these locations from being "blown apart" by the doubled up edge nailing in these locations. Also required is some space between the shear ply sheets. This prevents any buckling of the ply between studs. Earthquake construction is engineering intensive! Great job!

    @craigs5212 7 лет назад +4

    The HD anchors are usually used in pairs -- one at each end of what they call a shear panel or wall. The plywood and studs between the two posts with HD anchors forms a rigid panel even though its composed of a number of pieces. It is designed to resist loads (quake or wind) applied in-line with the wall. When a quake hits and the ground accelerates and moves in the same direction as the wall all the mass in the roof structure doesn't want to move -- this results in a linear force running parallel to the top plate and applied at the top plate of the wall. This force tries to tip over the wall by lifting one end, the HD anchors are there to prevent this uplift and the resulting damage. Most likely they used 4x6 not because of tensile strength but to provide a wide enough space for all the nails needed for a shear panel plywood nailing. The required length of the shear wall and the number used is calculated by the engineer when he does the wind and seismic loading calks. The normal foundation bolts generally keep the foundation from slipping off the foundation in horizontal sliding, they do add some uplift protection. But the HD anchors keep the shear panel from overturning. The 2x2 washers are new after 1989 because they found the old washers just pulled through the plate in a quake. Also they now require hot dipped galvanized bolts because they found the pressure treated lumber was corroding the bolts away. You will see the roof trusses will be connected to the top plate with metal Simpson clips also the roof sheeting will be nailed to the freeze boards (boards with the vent holes between the trusses) then the freeze boards will nailed and metal Simpson cliped to the top plate as well. All tension loads now are connected with metal connectors.
    The HD anchors are spaced off the sole plate so the 4x6 is always in tension, if the anchor were bottomed any shrinkage in the 4x6 as it drys out would allow slop space between the 4x6 and plate. Slop space allows things to accelerate in a quake. We have most likely gone way overboard but the structural engineers and Simpson make lots of money selling these things and then we have lawyers. So mr engineer why don't you tell the jury why you under designed the structure.

    • @martinpoulsen6564
      @martinpoulsen6564 5 лет назад +3

      They are held off the baseplate to get maximum hold down effect on the post, as when you tighten the nut, it will compress the washer and stretch the U shape bottom of the bracket. The post is holding down the plate - not the bracket. Given the room between the bracket and the plate, you can impose a lot more pressure on it, given the footprint of the post vs. that of the bracket, which is why it is so important to have a good grab with the lag bolts in the post. They transfer a lot of force.

      Hey Steven, I am not sure where you are coming from on this? I did not install these my builder did and every step of this build was inspected by the City of Clovis, not only is this building to code its was over built to avoid any and all building code issues. If I am missing something here, please inform me so that everyone will receive correct information. I'm not a builder that's why I hired one of the best in this area to build my shop. Thanks for tuning in and commenting. Best Regards, Ray

      Ray Caniglia Hello Ray, the bottom of the HDU should be in contact with the bottom plate, the plywood shear wall (actually a brace wall) should be run horizontally. The City of Clovis Building Inspector should have noted both. Will it work as installed, probably. Is it a 100% correct installation, no. The IRC as well as Simpson Strongtie have detailed design/installations for “Brace wall” depending on the seismic zone location for the installation.

      Thanks for the info Steve and am not sure why this was not called out during weekly and most important, final inspections. The shop has been up for well over a year now and I have not noticed any issues as of yet but will have my builder inspect them right away! Thanks again!

      Ray Caniglia You’re welcome, always happy to help. Some Building Inspectors are better than others and some, even though you might think they’re being difficult, actually care about the end-user and life-safety issues. I was a lowly Builder of 40 years, who thought I was following building practices correctly. A few years back I began my reinvention as an ICC Certified Residential and Commercial Building Inspector of which I am now. Not that I know it all, but I now know a whole lot more than I did my entire career as a Builder.

      @@stevenrich1819 Hello sir, I have a sheer panel wall with 2x8" wide studs that call for an HDU-4. I cannot find any information on whether I am supposed to center the HDU-4 on the center line of the 2x8 stud or is it supposed to be off-set 1 3/4" from the outer wall (as is standard with all the other 5/8" anchor bolts that hold the sill plate to the foundation)? Or does it really matter? Thanks, John in San Diego
