This is a typical section for a minihome. As I mentioned above there will be some changes to make this work for 100psf floor loading, including the floor sheathing.
Yes, that would help for sure. I've attached a typical cross section for a unit like this. Please note that some of the material will be different but the overall layout will be the same. For instance it shows a standard 2"x10" floor system, in this case it will be engineered joists
Have another small project. This one is a small construction office at a manufacturing plant, it will be permanent. The office will be basically a mini home (16"x34"). The floor system is typically 2"x10" supported by (2) 3 ply 2"x8" that run lengthwise with the floor joists cantilevering 24" on...
Thanks for the help everyone.
An update on the project, the client has decided not to place the hot tub on the elevated deck. To be honest that kind of makes me nervous. Hopefully they don't plan on placing the hot tub on the deck anyway after the job is finished.
Thanks again
Thanks for your responses. Should have been clearer, the balcony will be 12'x12' and not cantilevered. Was to be a standard construction (2x10 PT joists, composite decking. Supported by a multiply 2x10 beam which was to be supported by 6x6 PT posts). The deck will be end up being 13' above...
Have a question about a hot tub on a balcony. Have a client who wants a two car garage with a two bedroom apt above. The garage ceiling is to be 12'. They want a balcony off the main bedroom and then place their 6 person hot tub on that balcony (12'x12'). What things should the client be warned...
From my understanding unbalanced snow loads are to be considered when designing trusses for single family residential homes (ASCE7-10 Section 7.6). I work with a home manufacturer who designs their trusses as monoslope trusses. On site, when the modules are put together the monoslope trusses...
Not sure if this is the proper forum for this question but here goes
I believe in the US a window that meets all these criteria:
-The window measures more than nine square feet
-It has a bottom edge that’s under 18″ from the floor
-It has a top edge that’s more than three feet above the...
That's exactly what it is. Soon as the self-weight was removed the max span worked out to be 15'-3 1/2".
I agree with you on what dead load should be. Usually spec a dead load of 15psf or higher depending on the floor finish.
Thanks for spotting the issue.
I have a question about the 2015 IRC on joist spans.
Table R502.3.1(2) (residential living areas LL-40psf, DL-10psf, L/delta = 360) states that for a 2"x10" @ 16" SPF #2 the max span is 15'-5". But I have an engineered calc sheet (Woodworks Sizer 11 USA) that shows the max span is 15'. The calc...
Hello all,
I've noticed more and more that designers are specing reinforcement for concrete foundation walls. In this case I am talking about standard construction, nothing fancy. I am talking about single story or two story homes that are typically rectangular in shape, about 28'x 48'. No...
Thanks lexpatrie, that makes sense. We were thinking the only load carried by the ceiling joists was the ceiling dead load. But you are correct that there would be second floor loads transferred to the ceiling joists through the 2"x6" sill plate. We will continue to use the hangers.
Thanks everyone
Just to clarify any confusion about the drawing requirements. The drawing does say "No hangers". But in this case it isn't a spec from the designer but a request to verify if it is necessary. They had been using hangers for years but have no specifications that stated that in writing.
Here is the section, I tried a different browser and had no issue. Must have had a pop-up blocker turned on in my original browser.https://files.engineering.com/getfile.aspx?folder=5f89e616-fa9a-4c20-b948-d5adedb9fe4d&file=image001.png
Hello All,
Been working on a few projects (two story manufactured housing in Canada). Due to the way the homes are put together onsite the main floor modules have 2"x6" ceiling joists. These joists only support the gypsum ceiling. The joists are fastened to a sill beam and rest on the top of...
Thanks again to all,
Thought I'd just follow up with what we will be going with. We used the same spans as shown in the pic above. But, we used a 3 ply 2"x10" set at wet service and pressure treated SPF#2 (Southern Pine isn't readily available here in eastern Canada). The contractor wanted a...
Yes, Top set at continuous and bottom at supports.
Please find attached the calc output.
Thankshttps://files.engineering.com/getfile.aspx?folder=5fc689db-830c-4b90-aaf5-1285260b2ae0&file=2.pdf
The first pic (taken from the web) just shows the basic idea of what the beam is and how it is loaded. The second image shows the actual beam with the sonotubes (the drawing shows the supports as 6" Lumber column but it will be sonotubes. Does this make more sense...
Sorry, I didn't clarify that we are located in Canada and probably not clear on the beam either. The beam is a lumber beam, 3 ply 2"x10". The loading is applied vertically on the top of the beam so I figured the top of the beam would be under compression and the bottom under tension, am I...
Have a situation where a deck floor (with roof) is supported by a 3 ply 2"x10" beam (floor and roof loads). The floor joists bear on the top of the beam and the bottom of the beam isn't laterally supported. The beam doesn't pass without lateral support on the bottom edge (tension). If there is...
