I don't know if this helps, but I use this product for slide bearings in building expansion joints.https://files.engineering.com/getfile.aspx?folder=005b0636-b150-4ff4-bbc7-a72bd60ec941&file=Fluorogold_Slide_Bearings.pdf
You can't even begin to evaluate the drilled shaft without detailed soil boring information. When I do foundations for high mast light poles, a soil boring is taken at every light pole location.
You might not want to spend the $950, but CivilTech has an excellent program for analysis called...
There is an excel spreadsheet program called GRDSLAB, written by Alex Tomanovich that is all over the web. It covers slab design for line/wall loads, as well as uniform loads, wheel loads, post loads, etc. The latest version, I believe, is version 2.
Since you're saying this is a retrofit, I assume the walls are not load bearing. If load bearing, the axial load creates significant additional bending moments, due to the deflected shape. However, even the wall self weight itself will slightly magnify the bending. See the design provisions for...
Thanks for the response KootK.
Oldrunner - the loads were given in my original post. I'm not sure what a D/C check is.
The stair detailer is telling me he can't have bolts exposed on the inside of the stringers.
One aspect of having the continuous vertical plate across the entire width of each end of each stair run is to create a rectangular stair assembly composed of both stringers and the end plates. The fabricator plans on adding a couple of temporary intermediate steel plates, tread plates if you...
I am designing steel stairs that are being installed in a wood-framed multistory building. The intermediate landings and floor landings are also framed in wood. The edge of all landings that I need to attach the stairs to are framed with (2)1.75"x11.875" LVL beams. The landing decking is simply...
There is additional information in the ASCE 7-10 Commentary on determining wind exposure when you have open patches around the building. However, I don't think you'll like what is says. Even though the commentary says that it is estimated that 60%-80% of all buildings are exposure B, all it...
dianium500, Where in the Florida Building Code do you see the 6 ft tall wall numbers you reference?
I was recently asked by a local contractor to design a 6'-8' tall (sloping grade) CMU fence wall on the beach in St. Augustine, FL. Using ASCE 7-10, Figure 29.4-1, Case C for Risk Category I (121...
Double oops! Of course, the force of the explosion is a function of amount of explosive material,the material's properties, and the size of the confined space. 30 psi could be right in the confined space of a silo. I'll let somebody else answer this question.
Oops! I was remembering wrong (been a long time). I think 80 psf was the design pressure on the explosion-resistant walls. It's an old document, but see the attached Factory Mutual document that addresses explosions and explosion...
30 psf is way too low. I designed a building in the past where flour was used for making cookies (flour dust is also highly explosive), and the scenario was to provide wall areas that would blow out to provide explosion venting. If I remember correctly, the wall sections were designed to blow...
I found this in the handout material I received when I took Blodgett's course many years ago.https://files.engineering.com/getfile.aspx?folder=6c9a34b1-3b44-4999-8d3c-488248295788&file=Blodgett_Weld_Line_Properties.pdf
oengineer... I'm not familiar with the Engineering Tilt-Up book, so I can't judge one way or another. It is available at the tilt-up.org website. it's $255 for non-members, and $185 for members, so it's definitely not cheap. The Hugh Brooks publication that KootK recommended above is 20 years...
