Ron is right. In GA, the statute of repose is 8 + 2 years, so you have to maintain coverage for 10 years after your last project because a claim can be made against you during this period. The problem is that there is no insurance that will cover you after you close your business for more than...
I’m closing a small engineering business that I operated for 4 years and I want to be on the safe side and get tail coverage. The statute of limitations is 8 years in my state. My insurance carrier says I will need to renew my policy for each year for 7 years and then get a 3 year tail policy to...
Following up on this. My model shows that the wall still behaves enough like a cantilevered wall to rule out the use of the smaller, typical footings that are used on residential projects. These smaller footings may be fine for walls that are braced by the first floor framing (not that the...
I have uploaded an image of the model that I created. One image shows the plate elements that make up the structure. The other shows the outline of the displaced shape (in green). This model has enlarged foundations. This model also shows stress contours for Mx, My, Base Pressures, etc. I...
I definitely don't want to cut corners. I just know what they typically build and was trying to find a way to prove/disprove. I can analyze counterfort walls easily. I can analyze rectangular tanks easily. However, this is somewhere in between. I doubt many people have gone through the...
This is a wood framed house with brick, but that could not overcome the lateral forces from the 13.25' of backfill from bottom of footing to top of wall.
I believe that I have read through all the previous posts regarding basement walls and I still have some questions. I am working on a 10,000 sq-ft residential home with a daylight basement. The total dimensions are roughly 85'x35'. The 85' sides have jogs in them. The 35' is a straight run...
XR250,
Fortunately, I do have some jogs in my wall and I have a garage slab that can resist a portion of the loads on one wall. I'd love to run a finite element analysis if I have time.

I'm doing a custom home build where the unbalanced retained grade measured from top of slab to top of first floor wood framing is 10'. I've reviewed all of the threads in this forum that are applicable and none really touch on this aspect. In '06, the IRC had a section that covered walls...
Thank you all for your responses. In regards to the through bolts, what length of the through bolt do you use when checking bearing on the concrete? It's not next to an edge, so concrete breakout shouldn't be a concern. I would think direct bearing would with higher concentrations of stresses...

We performed destructive testing to determine negative and positive, column and middle strip reinforcement sizes and depths. We also did ground penetrating radar to determine the amount of bars in the respective strips. Of course we also took cores for compressive strength tests...
dhengr,
Good point on the vibration - I will look into it. I believe the dead load and dampening of the conc floor will minimize the vibration. We have 9" thick slabs. It definitely would be the first thing to pop in my mind if this were a slab on bar joist floor. They provided rack cut...
I am reinforcing a two way slab for punching shear. I have reviewed several documents, mostly studies, for reinforcement options. The option that seems to be the most effective is a steel collar. I've attached a picture of one option that was used in a study. In this study, they roughened...
OHIOMatt,
I did consider the occupant loading in addition to the rack loading. If I were to reduce the live load factor on the racks, I would have to back out the occupant load and hit it with the 1.6 live load factor. You are right that I cannot predict what will happen, but if I provide a...
I have been working on the structural capacity assessment of an existing two way flat slab with drop caps. They are looking at bringing in a retail tenant that sales alcohol. The rack loads for the displays are very high. They disclosed the exact rack layout for the tenant. I took the rack...
