Yes, It's for a pole building MNDOT is using for vehicle storage and maintenance. Since the columns are interior supports they only need to be treated for the bottom 6'-8'. I am not sure how they ended up the way they did because I required the top of footing at 5' below the finished grade which...
I was just notified that a post-frame building I designed has the posts installed, but the treated section of the post ends about 3" below the top of the 4" concrete slab. This leaves the rest of the untreated column above the soil, but still against the inside of the concrete floor. I am using...
I'm in Minnesota and I engineered a custom home with a three story below grade foundation system on a lake. The owner owns a construction company and I had them install a permanent sheet pile retaining wall to lower the lateral soil load on the basement walls around the house. The foundation...
The wood species was given to us by the owner since his family built it when he was a kid and that's what they used. The wood is rough sawn 2"x8", and has the grain structure that I am used to seeing with oak, but yes, we would have to get it tested if we wanted to get a true determination of...
ChorasDen at this point the 115% is arbitrary to some extent since when we test crane loads, we overload them 110% for certification. I figured 15% would be better for the floor, but I also figured if someone else has more experience they would suggest a more appropriate weight. The building is...
XR250, I will try that, but the barn was built about 100years ago. It is in amazing shape considering its age, and the owner has been doing a lot of maintenance and repair work on it since he has been using the area under the main floor as a game room/man cave.
Thanks for the help
So ChorasDen, considering what you said and since we really don't know anything about the floor joists except the species, I am thinking we should probably stack a 115% of the desired floor load and physically load test the floor rather than try and determine the capacity through design methods...
I have a barn floor using white oak joists. I am trying to get a capacity for the floor, but in the NDS the bending stress for white oak is less than that of Spruce Pine Fir which is what we have around here. The problem is that I know that white oak is denser and stiffer for the equivalent size...
Dauwerda, I have instructed the contractor to cut a control joint at the step on the future slabs to be poured, because I thought the same thing as you. The soil at the step is sloped down so no reentrant corner unless they didn't follow the plans. This is the only slab poured so far, and it...
The thickened edge only has reinforcing in the bottom of the thickened edge. The slab only has fiber mesh in it. The cuts were made within a day of being finished.
I have run into a problem that I have not had brought to me before. One of my projects has multiple 40x150 storage unit buildings with continuous slabs. Each slab has a step about midway. The slab is 4" thick with a thickened edge perimeter, and the step is 12" thick. I went out and inspected...
