Load Bearing Wall Framing Basics – Structural Engineering and Home Building Part One




Click on this link if you’re interested in a few more of the videos I made on structural engineering, home building and construction. This video will provide you with what I consider to be a simple view of how a load bearing wall works along with a few structural engineering points on home building. The most popular video to date I have made has to do with providing a few tips about load bearing structural walls and this will be the first in a series of related videos to provide more information for do-it-yourselfers as well as professionals. Don’t forget to check out some of our other videos and visit our website for more information about construction and remodeling.

    so glad your informing and intimidating on this subject. I've seen contractors remove too many interior walls and wonder why their 2 story project is cracking up.
    should do one onload bearing and non load bearing trusses to inform as well.

    I understand that load-bearing walls transmit the load from the roof all the way down to the ground slab and then the footings underneath. I do not understand that the middle wall – without a footing – does not have any load on it. It is tied to the ceiling and surely some load (albeit perhaps, a small fraction) must be transmitted thru it to the cement slab. Why can only footing supported walls be considered as load bearing?

    Omg! Somebody kill me! My husband is driving me crazy about how to build a 40×50 slab! And a 30×40 footing for living quarters! Btw. We are on a mountain! Our steel building is 40×80… ?? ty

    can anyone please explain what's the different between
    Structural Engineer and Civil engineers.
    thank you

    Thanks for the effort in making these videos with diagrams and pics…. the more people can see and understand then maybe there would be less questions after they studied their structures? Anyways, knowledge is power and if I could request more of these sort of structural vids with some variations such as foundations and different soil types and how they manage loads etc. thanks again.

    Please stop apologising. As a first time viewer it made question whether this was going to be worth watching. You have some good explanations but presentation could be tighter.

    Great Video! Saludos. from the Great state of Texas! question, based on your video, a good way of determining whether the wall is LB or NLB is to assess through attic?

    I want to construct one floor on my existing load bearing house which is almost 30year old. Is it advisable to go for additional floor and if yes then what are the precaution to be taken care. Apart from it you can suggest alternative construction methodology

    I need your help. I just bought a 1950s brick house. and the whole thing is constructed with 2x3s. I wanted to replace all the windows and doors but everyone only sales things for 2×4 construction also I need to install insulation and it seems the only way I can pass code is with spray foam which is too expensive. and rigid foam. also all the walls are very thick because they have vertical tongue and groove planks on them with horizontal wood ferring strips behind them. I wanted to remove all the wood ferrings and tongue and groove to replace it with drywall. I don't know what to do!

    Can you show a diagram on how to connect two roofs together for a log cabin? In an "L" shape, the first truss on the left side of the horizontal stem of the "L" is on the load bearing wall. The walls on that addition are all horizontal logs. The logs will settle, so the roof connection needs to allow settling or it will pop apart and the metal will tear. The walls on the main part if log cabin have vertical logs that aid in support and don't settle. At a loss. It was not done correctly. A "master roofer" cut the engineered truss as he said it was higher than the others. It was designed that way to allow for settling. Another guy (framer) replaced it with laminate beam and built truss on top of it. But didn't tie it in to allow for movement.

    Footings should be about 200 mm outside of wall ?

    I want to open wall between the dining room and the living room.
    The wall is next to the chimney flue. Going up the attic I notice that the wall is going along with one of the ceiling joist. Is that a non bearing wall or load?

    Basic rule of load bearing walls. 1 depending on the age of the home, certain eras had standard building practices. 2 Look in the basement and see how the floor joists run (if a basic home with 90 degree (square or rectangular shape) will have a main carrying beam in the center, with columns supporting it. The main carrying beam will almost always have a load bearing wall stacked on top (continuous load path) on each floor. The picture of 1 long floor joist or ceiling joist (its a floor joist for 2nd floor way to big for a ceiling joist) is modern engineered lumber which is a overkill by engineers and Architects to sell much more expensive lumber, or they have little, to no practical application of real world building. In most cases Linear 2 X 4 or 6 8 10 12s are fine except in the case of long spans. That shown method of 2 floor joist bypassing each other is known as "Joists Over" and it is a very common method which you will see in your basement (if you have one) The basement framing most always mirrors the rest of the house. In homes from the late 1800s to modern times which use conventional lumber 2Xs will have walls that run parallel to the floor joists which are much less and in many cases little to no structural importance. In a case with trusses (engineered rafters which have webbing resembling the letter W all interior walls on the top level bear no weight or very little. Some non load bearing walls do take up deflection or sagging of compression load (weigh of ceiling it self), although proper lumber sizing should override this. Some plans (blueprints) drawn are not always correct like any profession not all architects know a whole lot about constructing a house and are more into the aesthetics, which in some cases are not structurally sound or practical roof lines most notable rafters are trickiest part of a proper design and require real world application experience or knowledge to some degree. In many cases when opening walls up and engineered lumber is called for usually the lumber manufacturer will provide you with recommend sizing for the structural need, engineer
    is usually not needed
