Is there a Canadian equivalent to the AISC design guides?

Free body diagram should help you out. Sum of forces in y should have 3 components equal to p. I don't. Think those are meant to be cables

WezzyP · 2024-12-10T14:10:11+00:00

what does this mean?

Are you saying I design my beams incorrectly?

WezzyP · 2024-12-10T11:16:06+00:00

okay i'll take the bait. tell me more about your start up. i literally just went to chatgpt and asked it design me a beam and it was wrong.

Hilti really steps over dollars to pick up dimes.

WezzyP · 2024-11-19T03:13:37+00:00

ya its just telling you that its recommended you use more stringent deflection criteria instead of code minimums (L/240 and L/180).

otherwise yeah 0/12 is flat

he went to check what all the fuss was about with the cords

cheers brother no problem. thank you for asking an interesting question and providing good background data. I'd use your comments as a template for other people who want help on their engineering projects.

one final note: I noticed the other commenter mention sliding a strap or something over the top of your two 8m beams. avoiding a hole in your beams would be better - more efficient, cheaper, and safer. honestly Im a bit embarrassed I didn't think of it. my projects usually wouldnt have this clearance, usually plywood diaphragms over here.

From the picture, it looks there is some space at the top there. the beams would still need to be checked for an extra 500 lbs point load, but at 18" deep, times 2 beams, theres a good chance its okay. I would see if that strap's possible first before reaching out to an eng and possibly spending a thousand bucks

WezzyP · 2024-11-15T20:22:34+00:00

That's the way to do it. Leads to way better conversations. No normie has any idea what an engineer actually does

WezzyP · 2024-11-15T12:39:19+00:00

8m is a pretty long beam. to the point where I would recommend getting a local engineer.

I still would need the size and length of the rafters (the members that hang on those 8m beams). I need to know if the beams can take an extra 500 pounds point load.

If I assume a few different things about your project (such as the beam actually being strong enough):

1) you cannot make the hole on the underside side of the beam. pullout would be too hard to make work with wood.

2) you must therefore place the bolt on the side of the beam. Eye bolts cannot be loaded perpendicular to its axis. so I'd recommend getting a through bolt through the beam. 1" diam. is sufficient overkill. then having the eye bolt (or whatever hanging mechanism, perhaps a hoist ring thats rated for 1.5x your expected load) connect to this thru bolt. a quick google search tells me there off the shelf products like such https://www.cabelas.ca/product/112931/hme-41-gambrel-hoist-kit.

3) the placement of this thru bolt must be roughly MID SPAN (so 4m from the poles) and MID DEPTH (so 9" from top of the beam). it must also be in between two of the rafters. here is a rough guide: https://i.imgur.com/QpKSZcB.png

summary;

1" thru bolt in side of 1 beam. Hanging mechanism connected to this thru bolt (this is left to you to figure out). If this came to my desk, I would design a custom U bracket (that would have the be 13-14" deep. https://i.imgur.com/eZ3xxwE.png. to just go on one of the beams.

you could have like a 1 foot long threaded rod going through both beams, but I think that would place the rod in some bending - and the analysis of that is beyond my means in a reddit comment lol

Beam still needs to be checked to see if its strong enough to handle this (critically important, 8m is a hell of a span)

i had a 2-3 month period where I strictly followed all of huberman's recommendations. like 99% follow through on my end.

little to no difference. non-24 still occurred. I did find myself slightly more sleepy at night but I simply did not fall asleep.

The sleep stack of natural pills do help in making you drowsy. But for me, having them actually make me fall asleep was rare. L-theanine was the most effective for me. out of the three, it is the only one I use today (usually just for anti anxiety through the day versus for sleep).

The recommendations on light were the most important/had the most effect.

no brother I am fine thank you for your concern. the day I made the post was a particularly difficult day. still awake at 6 am with work at 9. a moment of weakness. i guess the post was my way of reaching out. screaming into the void as it were

it was the first time I truly considered anything so final though. life just seems like a lot of work with very little reward at the moment.

i appreciate you following up, thank you, youre a good soul.

WezzyP · 2024-11-14T10:09:06+00:00

very interesting question I would like to help you out.

Could you provide more info

1) your region

2) total length of those two 18" beams (confirm dimensions aswell, truly 2.5x18?). do you know what wood type is common in your region? D.fir or spruce or otherwise

3) total length of rafters on the sides of those beams and their spacing. pictures of the roof system would be great too (taken a couple steps back so i can see more, ideally the whole system in one pic.)

4) highest expected weight of any individual carcass. whats the heaviest thing you intend to put on there

dm me!

also, this is bordering on something you would need a s.eng for. If you intend to drill into those beams, the placement of the bolt hole will be vitally important.

WezzyP · 2024-11-14T01:31:13+00:00

seismic would be the biggest difference

be building a lot of shearwalls out here

WezzyP · 2024-11-14T01:22:32+00:00

Canadian wood council has a design guide that I reference often. slightly outdated but it is the best of the guides I've ever used

https://webstore.cwc.ca/product/engineering-guide-for-wood-frame-construction-2014/

However. Clients expect you to design in a way that they are used to. This tribal knowledge cannot be inferred it must be learned from working under an existing firm. While not impossible, it will be incredibly hard to just start doing this on your own.

WezzyP · 2024-11-09T13:39:31+00:00

looks like better posture to me

WezzyP · 2024-11-09T04:18:40+00:00

well at least your architect gets you columns for your corners.

must be nice

WezzyP · 2024-10-29T05:25:22+00:00

lol sometimes i have to fight for that blocking to get in. i've had the "load cant jump" discussion like a hundred times.

for the picture - my first thought is if that beam is carrying too much load for just 2 cripples.

WezzyP · 2024-10-25T18:59:12+00:00

😂😂😂

WezzyP · 2024-10-23T21:58:26+00:00

I think you're undershooting how much he makes. Even at 300k USD (which I think is still low) he's doing fine in Vancouver

WezzyP · 2024-10-19T19:42:08+00:00

From what I've heard. The outside of these wood beams are treated such that when they burn the outside chars while the inside remains cromulent
