The vertical jumps now look at lot better. So far it seems pretty solid:

Spent the last two days adding in some additional code so that the vertical jumps in the shear graph (at point loads and supports) are actually vertical. It was a bit more complicated than I originally bargained on but I think I finally have it figured out:



�The code seems fairly robust but tomorrow I will throw the kitchen sink at it to see if I can find any weaknesses in the algorithm.

I have't been posting much lately but that is because I've had my head buried in the code.  Most of this engineering code is completely new (not my typical plugin stuff) so there is no refactoring old code or any other shortcuts I can take.  Some of the old beam calculator is relevant however since it was so limited in its application I'm kind of on my own with this new calculator.

New to the forum, very interested in the 20 x 30 1.5 story plan; I have a lot with well and 1-bedroom septic in place, envision one bedroom down, open loft/office above and cathedral over the living room. I would be building on a full basement for workshop and storage; is is possible to do U-shaped stairs to code going up to the loft, with a matching set below going down to the basement? Has anyone done this? I'm in MA, the code does allow 8" rise with 9" run which would make the stairs more compact than 7"/10". I imagine this topic has been covered elsewhere on the forum-- thanks if you can direct me to relevant discussions, plans and photos!

I haven't updated this thread in a while.  Put on a tin roof last fall, and working on the siding now.





First time using the forum to upload images. 
I was using Imgur but I also lost access to those.  

The siding is actually done on the front and sides, just working on the back now.  Takes time to cut around stuff, like these custom boxes where I am storing my diesel heater and fuel tank.  



Still need to route the muffler and intake properly, hopefully before it snows.

First look at the bearing check:



I also need to update my disclaimer, the disclaimer shown is for my previous online calculator, it needs some changes.

I don't have a lot of advice for you, but try to think about having everything do multiple jobs.  Fold down table, table turns into bed, vertical custom cabinets, loft for storage or bed, building supplies under cabin, build a shed.  

Good luck

Hi everyone,
I'm thinking about building a small cabin or micro-cottage, and I'm wondering how you organize the space to make it really practical.
I'm mainly thinking about storage and managing supplies, so that I have enough to last a few days without having to run around everywhere. Even a small stock of long-life meals (like the ones you can find on freezedriedandco.com) can quickly become cumbersome if you don't think about it from the outset.
If you have any tips for optimizing space and keeping the place functional while maintaining a minimum of autonomy, I'm all ears!

Working on assembling the actual engineering part of the report now, adjustment factors, shear, moments, deflection and bearing checks.

Version 0.8.2 - 09.09.2025
- Enabled loads and reactions (values) within the load diagram.
- Fixed a bug with end supports that are not centered on the start or end of the beam.
- Improved the formatting logic (SVG and HTML) for the load diagram.
