Recently diving back into the bizarre world of the slab on grade(ground) design. I have been pouring over ACI committees, reading papers and reports, and I am trying to gather my thoughts into one post. Hoping some additional discussions/opinions will clear up some uncertainties about the design...

I have been doing quite a bit of research on Cold joints in concrete beams, however, I have a more particular problem than i found that can be addressed in some of the forums. Looking for a second opinion. I have a concrete beam that is torsion controlled. There is a 5' cantilevered balcony...

Hookie- thanks for your reply. that is a similar concern I had after reading more in-depth about the sorel cement. Appreciate the feedback

Does anyone have any experience in projects using Sorel Cement? I am having a hard time finding literature relating it to structural engineering applications/elements. I have several concerns with taking on this project. There hasn't been much testing with Sorel cement applications so I have...

@olddwag, thanks for the advice.

Thanks Dik, that seems like a very logical and conservative solution. Appreciate the feedback

I have recently inspected a building, that has severe corrosion effects, and it got me thinking. Are there specified code limits for oxidation depths? I have read a few articles about the rust of enclosed sections (box girders, hss members, etc.) but I am dealing with w/h columns in a braced...

Good reminder for the uplift, I had not yet considered that in my calculations. I will be using hoops and adding additional longitudinal steel to resist any torsional moments.

I have a concrete beam, 8"Dx32"W spanning 16'. I have a concrete "eyebrow" cantilevering off the edge of concrete beam. This is causing a torsional load on my beam. On the other side of my beam I have a floor system that is bearing eccentrically on an embeded steel angle causing a torsional...

hetgen- The wall is 11'-0" tall with the garage doors being 8'-6" tall. progammingpe - this makes sense to me, running the way I have it is more conservative than running each individually as a propped cantilever, and it works with my current top steel, so I think i am going to stay with my...

Working on a simple residential project, and came across a weird question with concrete beams. I have a wall that is 50'-0" long, with (2) 18' wide garage doors and a 5'-0" wall in between the garage doors. Due to loads and available depth, I have designed concrete beams to go over these...
