    PCA Circular Tank for Vortex Drop Structures

    This definitely helps. @JedClampett, I've seen some of your other posts mentioning the hoop stress in the bottom slab. I will definitely add those circular bars. From taking a deeper look at the PCA tables, it make sense why I've seen design examples specifying smaller amounts of flexural...

    PCA Circular Tank for Vortex Drop Structures

    Yes. The inner components will look different, but yes the picture is correct. Thanks, I could try to input some winkler springs, however determining spring constants seems to be a bit of a rabbit hole. If I understand correctly, it is a function of the depth, FE plate sizes, and expected soil...
