That may be the case. But the designs of the concrete walls I'm seeing are in text books. Would seem intentional. Could the theory be that the back side of the wall is deeper than 3ft. and therefore the footing is already kind below frost depth on one side?
I've seen a bunch of premade block walls with their standard footing only being about 16" to 18" below grade. I've also seen some older books with standard retaining wall designs showing footings for concrete or masonry retaining walls also only about that depth. Is there any consideration for...
In the end, that is what I did. I would like to follow up to whoever sees this and point out that you also have to calculate the governing loads of the light gauge steel (tension, shear, screw bearing, pullover, etcetera...)
Does anyone know of a good reference to calculate the shear strength of a single fastener in shear in plywood? I tried looking at NDS, but nothing really comes to mind. Trying to connect a light gauge strap to sheathing. The tables for the sheathing in NDS don't really apply because the way the...
At first glance this seems it would answer many questions. but after reading it, it leaves some questions. for one it was not really a true hip roof. what was the bottom framed to? how were the rafter jacks connected for the hip side? I know im sounding negative. but I do actually appreciate you...
Right so the ceiling joists perpendicular to the ridge pick up the thrust. I was talking about the jack rafters. those have quite a bit of thrust in them. And the last ceiling joists at the end of the ridge beam arent detailed or fastened with enough connected to carry that thrust. At least not...
I'm sure this topic comes up quite a lot. I have seen soooooo many hip roofs framed. We all know about the lateral thrust at the corners/lower support if there is nothing holding up the edge of the ridge or if the roof is framed with trusses. So why in the world are these roofs still standing...
There are special inspections required by code for certain construction. The question is who is enforcing the inspections. The inspections need to be done by a third party engineer who is qualified.
Good job on the building departments. For valley beam, I found myself explaining snow drift in two directions and having to use much higher loads. When your rafters are TJI's and your spans and over 20ft......
That's a really interesting point! Should IBC design require IBC inspections in a residential construction?. In chapter 17 some sections have exceptions. Was there a specific exception you were talking about?
