Very good video on explaining how to calculate column footings. Interesting product using a large steel plate.
This is exactly what I was looking for, thanks for posting!
I really wish I found your videos a month ago. Instead of going back to "night school" and taking a personal crash course in civil/structural engineering. You explained everything that took hours of research and calculations to determine doing traditional research and horrible RUclips videos... lol Great explanations. I will definitely be purchasing some of your products as well, should save a ton on labor. And, allow for upsell and easy code approval.
Sorry, for the late response, but thank you so much!
Awesome. Thank you. Just what I was looking for!
Very good video and simple explanation, it is almost like you read my mind on what I need it help with
Great Video thank you!! 🙏
Please make sure to address the rules of continuity when figuring your point loads, This could change the point load created by the joists and the beam. This can increase each load by as much as 25% and by more by the time you get to the footing.
Hi, thank for the presentation.
I'm going to self build a log home and the freezing line is at 5 feet.
I know that I'm going to have 28 piers of 36x36in at he bottom with 12x24in at the top and 3 piers of 48x48 with 12x24in at top.
Because I need them 12in above the ground I'll end up with huge/tall footings.
My question is should I made them in steps or sloped/obelisk?
My home is going to be a pass and but metod, staked with rebars (every 2 feet).
The size is 40x40 feet (the horizontal logs should actualy 42 feet long with minimum 8in diameter at top and 18in diameter the bottom) with 2 story and an livable attic.
The soil is a mix of clay with rocks and in the winter we got snow (a lot of it).
Thank you.
really well explained
Thank you!
so for a two story the post would have to support 12000 Ibs?
at 11 min you said 20" x 20" x 12" thick footing (where did you get the 12" from?)
12” is a safe thickness for footings up to at least 24” x 24”. The thickness of the footing is governed by the punching shear, in other words you do not want the post to punch through the footing. At 12” you are safe for smaller footings, In fact you could potentially go all the way down to the code minimum of 6” but usually I see, 8”, 10” or 12”. To determine the actual footing thickness takes a bit of work. Hope this helps.
your figures for bearing capacity are questionable.
Your questioning of his questionableness is questionable.
