Thank you all for the replies. The last building we did was not exactly just a box, it was 'L' shaped and had three different roof heights, but there were a few different baseplate/anchor combos for similar frame lines. There are certain load combos that can be eliminated by inspection, but...

I just posted this in the foundation section of the Geotech forum, then I realized I was in Geotech and these are more structural questions. I have a few metal building foundation projects coming up. On the last foundation I did for this company, there were 15 to 20 different base plate/edge...

I have a few metal building foundation projects coming up. On the last foundation I did for this company, there were 15 to 20 different base plate/edge distance/reaction combinations. For most of these, there were 8 or so wind reactions, 2-4 seismic reactions plus the dead, live and collateral...

Ok, thank you all very much for the input.

Is the .5%Ag for each direction or total for both directions? And does it include bottom rebar or just top? ACI 360 recommends the rebar be placed as close to the top as possible, so it makes it sound like it would just be the top but a #8 @ 12" grid just on top seems excessive for crack...

So if you do not provide any joints, or a minimal amount, you rely on the top layer of rebar to control the cracking? So you would end up with tiny cracks all over the slab but no (ideally) significant cracking? And if we were to go with joints, you would discontinue most of the rebar so it...

I am working on a slab on grade design for a PEMB. Slab will have turned down perimeter footing and will be poured monolitically with column footings. Soils are not ideal and there will be heavy equipment loads (forklifts, loaders). Slab will be 12" with double mat of rebar. So how do the...

Great. Thank you very much.

Anybody have any experience with a project like this?

I am working on a one story residential concrete structure. This is my first concrete structure and I am looking for a good reference or two to help in my design. I am particulary interested in lateral design of the structure as there are a lot of openings, so the shear wall segments are...
