Hi, I have a few questions about the design of a core wall in ETABS. I assigned the core wall element with a 'core' pier label and then defined the general pier section in Section Designer. See figure 1 below.
Question 1:
Question 2:

Question 1:
In the interaction diagram, it appears that M2 is 0 due to the symmetric layout (see Figure 2). However, in the design report, the capacity is normal, i.e., no failure is reported in P-M2 (see Figure 3). Why is this happening, and how can the interaction diagram be 'fixed'?

Question 2:
If the design load combination includes seismic load cases in both directions, the design actions on all legs are the same (see Figure 4). Why is this happening, and how can I fix it?
