Construction details for a 4-ply built-up beam according to the Ontario (Canada) Building Code.
Just install 2 or 3 flush beams on the short sides and have no posts.

Thank you so so much for this very informational video :) I'm using this information for a competition tomorrow
I'm sad to see only three videos! You do a great job of explaining these building concepts.
Hi Trades Tube is this still code for 2024 for Ontario building code? Thanks great video.
Hmm, I notice there are no continuous beams spanning between the interior posts.. so you are seriously relying on how well the beams are fastened to each other to support the midspan. Personally, I would rather seem a hybrid system, where there are at least 2 beams with no joints over each span.
Nice video. I hope you will post further wood construction videos.
There are other ways to find out the amount of the drop . I will leave some ways to calculate it .I did some study and came out with this: If you like trigonometry , I will give you a way to do it : Hip drop = Hip angle tangent times half of hip thickness.I need more time to explain it but if you like trigonometry you will get it .Another way and very easy is the way explained in this video very clearly and very understandable .I give you another way which is : ( roof pitch times hip thickness ) / 34 in other words you take the value of the roof pich the way is noted on the blue prints weather is 6,8, 10 etc , you take that value and multiply it by the total thicness of the hip and then divide that result into 34 .The result is in inches .That way you also get the amount of hip drop .There is another very easy way but It has to be shown having the wood on my hands or on a drawing .That would be the easiest .But I hope you can use any of theses including the one shown in this video
Thank you so much for this video! Great information!!!
Great video !
Curious about the software you are using.
No discussion of the birds mouth cut? B.s.
Greg is my hero
Ha Ha! Thanks Kev
Thank you exactly what I needed to know. Perfect, to the point, excellent display ,just perfect, thank you
Very well explained 👏 👌. Thanks for sharing 👍
Great video, makes me think that someone should make a Framing Simulator game. That would be sweet.
Could this work with beams that spans the full distance using no joint beams? And what about milled lumber as a complete beam at that size and length?
The joints are according to the National Building Code of Canada and can only be used when there are posts, not full span. You'd probably have to get an engineer involved for milled lumber.
would you use the same method to determine how far you drop a valley rafter?
If you mark the "Stand" where the centre of the valley rafter is over the inside corner of the wall plates the centre of the valley will be the correct height and it doesn't need to be dropped.
Can I put any of my joints on top of my post? Or do they all have to be quarters? Say I do my first ply all joints center on the post. Then 1/4 rule 2nd ply and 3rd ply
On a 3-ply you can put the middle ply joint over the post and put 1/4 point joints on the 1st and 3rd ply on opposite sides of the post. On a 4-ply you can put the 1st and 3rd ply joints over the post and put 2nd and 4th ply joints at the quarter points. Built-up beam construction is described in Section 9.23.8.3 of the National Building Code of Canada which you can find free online at nrc-publications.canada.ca
@@tradestube5478 thank you 🙏🏼 and thanks for that link
@@tradestube5478 great video, exactly what I was looking for to create a 3 ply 2x10x20 pressure treated beam. Now I know to put 10 footers in the middle sitting on the post and 2- 12 footers on the outside but opposite to one another with 8 footers to finish it off! Thanks a lot, hard content to find!
Btw… would you PL everything together and nail or just nail? Thanks again!
@@stoneywilliams1209 How long do these wood come in ? 10 foot ? I want to make a garage. Need a large span. Is there a 14 '?

The sole reason I enjoy UTube is education and there is not reason why people can't learn new skills to free themselves from their self-imposed non-learning situation.
Thanks for this explanation
Thank you SO MUCH FOR THIS VIDEO!!! I need it for my exam starting in 20 minutes😳

Never heard of 1.4142?? Too much time to waste in here.
Bevelling the hip is not too much work when you know how to do it. 2 cuts 4 minutes.
Hi there! Great video, love the content Quick question just to be on the safe side: If we cut back the corner of the double top plate and the top plate, then the birds mouth comes closer so in this case there is no need for dropping the hip on the bird's mouth right? As I see it in that case the HAP will be the same as the jack's, since they are lined up at the same edge on the duoble top plate - is that correct? Thanks so much! I appreciate it!
For anyone stumbling on this comment, yes that is correct. The calculation for hip drop is setting back the framing square half the thickness of the hip which is 3/4" for the 2x here, then marking the higher seat cut. If you clip the wall corner, you are doing the same thing, setting the birdsmouth back 3/4" and just make sure to set the heel stand or HAP the same as the common rafters adjacent it.
How to measure hip roof square feet
The long sides are trapezoids and the ends are triangles so you can use those formulas to calculate the area. But also, the area of a hip roof is the same as a gable roof of the same dimensions.
Please give me drawing or video measurement square feet
Thanks very, very, very much.... So, so, so clear! If you get time to make more, I and I'm sure others would be hugely appreciative of.
Oh okay now I knew why buying a home is not cheap😆😆😆one miss calculation is gonna cost a lot more money.
where is the best place to find out about this stuff in Canada? Quebec specifically, I want to make sure I'm designing this right. I can't find anything in most of the literature on-line...
I’ll be putting my beam splices over my posts, alternating posts. I dunno what’s up in Canada lol.
Ontario has a pretty stringent code. This won't be a problem.

Bad talk
Great tutorial, need next video.
I'm building a 4 ply 2x12 beam for a 48' deck and this is very useful. Now I just need to figure out if this works in Alberta as well. Thanks
Very well explained and a good video!
thank you very much

Hey what happened to the videos man? There’s are very well made and informative. I’ve been looking all over for this to be explained.
Great video very well explained. Leaving me with no questions about what you said.
Very good information and well explained! I'm still picking up other people's tips and tricks at 60. For some of the other viewers who are interested in roof construction in different countries or who may even travel to work in other places. On the point where the crown rafter meets the end pair of common rafters, in good practice, we would face this pair of rafters up with a triangular "saddle board" a type of gusset board for the hip rafters to rest firmly rest against to ensure that they obtain full bearing because the hips can sometimes have a plumb cut about 1/3 longer than the common rafter plumb cuts. The crown rafter in between is also built down with a triangular block of the same rafter thickness and this enables a longer plumb cut on the crown rafter similar in length to the plumb cut of the hips. Therefore we adjust the position of this end pair of rafters to allow for the thickness of the saddle board and the hip rafter length calculations still meet at the center of the roof on the plan. Where the hip rafter meets the wallplate it is standard practice for us in Ireland and the UK to notch the hip rafter over a corner tie, or dragon tie, a very secure tried and tested method.
And also nail a off cut to the under side of the crown rafter.

Where is the best place to learn about fastening practices for four ply like this?
dude this channel is awesome, just started cutting hips and i had so many questions, Bless you
About wood deflexion videos? Will greatly appreciate your help. Thanks.
Hey There Trade Tuber, are you ok if I show this video to some young apprentices. I like the way you can see the dropping of the hip. Merle
Yes, go ahead, this video is intended for apprentices.
Take the dihedral angle off or commonly known as backing the hip rafter off
that's the way we learned it in school.....great video with no bullshit...
I have an old house 140 year old to be exact. It seemed like someone removed a load bearing wall many years ago, hence the floor on the second level sagging. I would like to add a beam to make it stable again. The span is 12ft . Would three 2x10 with plywood and glue in between and a combination of structural nails and screws be enough? Thanks
Finally! I found exactly what I was looking for. Thanks for the detailed explanation.
👍 good
This would be an awesome video if you can hear the f*** what he's saying
Very informative and not a whole bunch of useless talk . Just the facts ,not wasting viewers or students time . GOOD JOB !
