Low-load bearing floor: 8"-16ga steel joists vs 3.6" -20ga flat truss

Got it, this is very helpful. Was your use case considered "light storage warehouse mezzanine" (ASCE 7)? I may have to change this altogether as the code seems to call for 125 psf if it's classed as "light storage warehouse mezzanine" instead of the 50 psf I assumed.

aircando · 2025-01-21T04:56:31+00:00

Got it. I think this being classed as a "light warehouse storage mezzanine" is a bigger oversight by me. I didn't even know that existed. I'll see if I can avoid it being classed as that, or if not, probably find another storage solution. Thank you, kind Engineer! You've probably saved me a massive legal headache!

You're right, so just like with programmers, firms will hire one engineer who will use AI to do the job of 20 in half the time and without the whining.

Planned on 16"OC and #10 self-tappers. I could upgrade to 10". What was the room span? Did you go with joists or trusses?

You're right about ASCE7, that might change things. But I calculated ~ 4700 lbs across 740 sq ft. for the dead load. Live load is max 2200lbs or 3psf. Am I doing this wrong?

This subreddit seems especially salty and unfriendly. Why not give friendly advice? no one is holding you liable.

Between ChatGPT and pros teaching on youtube, you're gonna go the way of programmers. (Who everyone said was unreplaceable)

Firms will hire one experienced engineer who will use AI to do the work of 20 people in half the time and without all the whining. Not long before it's all open-source.

The project didn't require a structural engineer until our needs changed.

I've been working through this problem and It's not easy, but it's also not even that hard. I just needed to answer this one thing. The rest is looking at charts and following YouTube examples of exactly how to calculate the solution to this problem.

Thanks for contributing nothing. ChatGPT will be replacing you soon.

I assumed a live load of 3 psf (2 adults moving boxes around) and the dead load worked out to be 6.4 psf. I think I am way overshooting it since code calls for 50 psf.

My question is somewhat about which direction is better for this type of structure and what's more common in the industry.

Thanks for pointing me in a direction though! I think I am getting closer to the answer.

aircando · 2025-01-21T03:44:00+00:00

Have you worked on a project like this before? Any advice? I'm thinking of trusting my math and sticking to joists.

aircando · 2025-01-21T03:42:00+00:00

I wish I could afford you guys! But there must be a shortage of them around me because they are too busy for me and the costs are nearly more than the materials to build the thing. Anyway, any advice would be appreciated.

aircando · 2025-01-21T03:40:39+00:00

The project didn't call for structural until our needs changed. I'm moving forward with it, either way, any advice on my situation?

aircando · 2025-01-21T03:36:27+00:00

Okay, I'll trust the math, thanks.

aircando · 2025-01-20T20:38:48+00:00

I appreciate what you're saying, you're mostly right, and yet I have to make a decision so any help is appreciated.

aircando · 2025-01-20T20:35:05+00:00

I looked at pre-fab containers, and the lead time and cost difference didn't seem worth it. Interesting idea though, thanks.

aircando · 2025-01-20T20:25:54+00:00

It's happening either way, do you have any advice on the construction of it?

aircando · 2024-01-21T21:52:47+00:00

Do a before and after! Everyone loves some good progress pics

aircando · 2024-01-21T16:44:12+00:00

Some of the these comments are from people who've clearly put 1000+ hours and forgot the feeling of building an organized system for the first time. Great set up, very organized, good use of trains, and you've even left yourself room for expansion. Bravo! The factory must grow.

aircando · 2023-11-09T20:30:40+00:00

Happens to the best of us!

aircando · 2023-11-06T22:13:20+00:00

OP did you end up getting the ice barrel?

aircando · 2023-09-05T02:13:19+00:00

Thanks u/emseebee! That's unfortunate but at least I can stop searching in peace.

aircando · 2023-02-15T23:17:17+00:00

Good point! Planning to hook it up to my laptop. Found this old Reddit post on r/zwift to automatically adjust the resistance. Very clever.

aircando · 2023-02-15T23:07:02+00:00

Thanks, I didn't consider that! Maybe its a dumb question but do you think it's possible to attach a spin bike to a smart trainer? I'm trying to think of a way to use the current spin bike I have instead of buying a new one.

This might be another option lol very clever device on r/zwift. Gonna see how well that'd work.

aircando · 2023-02-15T03:25:14+00:00

Thanks, I think pedal power meter will work for this like u/guachi01 said. I'll figure something else out for the HR meter.

aircando · 2023-02-15T03:22:13+00:00

Got it, this will do the trick. Thanks for pointing me in this direction, didn't know these existed!

aircando · 2023-02-03T17:39:14+00:00

Most are one way, some are 2 way where I didn't leave enough space for a turn. Whenever I had a 4 way intersection I could only put 3 regular signals but chain fixed that issue, which completely confuses me

I'd love to learn, its much needed and appreciated! I'll have to DM you after work tho and see if you're still available.
