****This question was submitted by an ASCE member. I'm posting here so the entire community can benefit from the answer. I am conducting a new analysis per ACE7-22. While imputing the Soil Classes I noticed two different results.
Using the hazardous interface inputs I tried both site class C and D, I then received different results as expected except for the Seismic Design Category - Both resulted to “D”.
Should I be using D?
