Description: In this introductory lesson, we'll talk about the importance of shear walls in building construction and why they are essential in resisting lateral forces such as wind and earthquakes. We'll demonstrate the three forces that wind or seismic exerts on the building, and we'll show you how shear walls on either side, the roof, and even the floor system help to distribute those forces. We'll also explain what racking, base shear, and overturning are and why preventing them is crucial in preventing building collapse. We'll show you how to transfer the inherent rigidity of wood structural panels to the wall to make it more resistant to lateral forces, and we'll discuss the different types of wood sheathing you can use to achieve this. Join us to learn more about shear walls and how they can help protect your building from natural disasters.

Please remember that I'm not showing the best way to do anything, but just the method that works well for us. Thanks for watching!

Oh and another takeaway, if you use a drone for commercial work, you need to be part107 certified. Commercial work includes social media like YouTube if you plan to make an income off of that. I watched a video about this last May and then purchased the Part 107 Course sso.teachable.com/secure/245841/checkout/1320802/b… I studied and learned for 1 month and then took my test. I scored a 95%, which is a testament to how good Greg and the crew over there teach. That link will save you $100 off the course and support this channel.

    I'm a structural engineer! This video was great, and thank you for also sharing the different screenshots from the NDS publications as well! I love it!
  • @timkrouse345
    I work in demolition and you are making my job REALLY difficult. Thanks.
  • @FutureFaz
    I’m a licensed structural engineer in California. This video is fantastic. Great work!
  • @rayjackson4547
    I am a carpenter and home inspector for about 40 years. You did a nice simple job of explaining the system
  • @randallrogers8183
    Thanks for staying on site after work hours to educate us. That was incredibly helpful.
  • @jasonwrex
    I saw a couple houses collapse in my time as a builder by other builders. It was always from new crews who didn’t understand that you can’t rely on braces to hold an entire house with roof set. Sheathing and decking are your friend, sooner rather than later! Good video.
  • @seanlarson8968
    This would be a great practical video to show in an intro to statics engineering course. Very nice example with the simple starting wall. Then get into the individual and total nail shear forces, so nerdy! Love it.
  • @evan-edstrom
    Very true about the field nails holding the panel to the framing! I had a project framed with Zip System sheathing where the sheathing got a little wet during construction, and buckled in or out between each stud up to 1/2" in deflection. But the sheet itself stayed firmly attached to the studs.
  • @tubewatcher5012
    Thank you for the education. Met with a structural engineer last week to verify load bearing wall and received a significant education that I wish I had received decades ago. Wish I'd have taken my education more seriously and followed engineering.
  • @stipcrane
    Great presentation. Just learning the terms (Overturning, Racking, and Base Shear) is helpful in understanding better and being able to describe what most of us intuitively know. Construction is full of urban legends regarding the code and engineering. It is wonderful to get the straight scoop from PEs on how various forces act upon structures rather than the BS at lunchtime when framers pontificate about science.
  • @medicbabe2ID
    0215 and I just sat through an excellent video on shear walls, and learned a lot of new information & terminology. My day is going well already.
  • @cwu1999
    This is an awesome video. It really helps visualize the theory behind shear walls. Thank you for putting it together.
  • Great stuff. I've been designing homes for over 30 years and have built several in that time, and I was always taught/told that the sheathing should go perpendicular to the studs. This was very enlightening. Thanks for the mini tutorial! Never too old to learn new things.
  • @Happy-ze4bm
    One of the best videos and most knowledgeable I have seen. Thank you for your great work. you are a awesome framer. God Bless
  • @JayZoop
    Nice info! Thank you. People need to calculate the forces "during" construction too, not just the final building.
  • @MitzyChrisp
    You’re a terrific teacher. Really appreciate the video! Well deserved sub
  • @texasRoofDoctor
    Great stuff. I am building a cabin with my son and we are standing up the walls tomorrow. Wanted a refresher before we sheathed them.
  • @markturner5207
    I live 30min off the coast in Texas. My framer installed 2 shear walls in my home. 3/4” plywood and bolted in the slab. It is relatively cheap to do this and adds so much safety and security.
  • @Rizik1986
    Just found this video and subbed. I just learned about these various forces. I built a small 4 x 8 raised deck to catch rainwater in barrels on. I braced it figuring I'd have racking either from back to front or from side to side. A light rain easily filled the barrels. Roughly 450 pounds of water in each 55 gallon barrel. I thought 2 x 4s I had left over would work. Nope! A couple 2 x 6s seems to have worked. No more racking.

    I have a lot more to learn! 👍🇺🇸🍀

    Wow, very, very educational. Saved to favorites for future use on my Desert Homestead. Thank You!
