Hello -
I have a CMU shear wall supported on a pile cap running along the length of the wall. I want to determine the reactions at the ends of the panel to design the end zone rebar. I have experimented with:
1) Continuously pinned along the base
2) Continuously pinned along the base AND explicitly pinning the two joints at the ends of the panel
3) Only pinning the joints at the ends of the panel and leaving the base of the panel as a "free" edge
Question - What is the most accurate way to support the wall panel to get this load? #3 makes the most sense - it will give me reactions at the ends of the panel. #1 and #2 gives me a "distributed reaction" along the panel. I'm conflicted because #1 or #2 seem to be the most realistic but I don't know how to get the end zone loading from this distributed reaction.
And a related follow up question - What if I have one long shear wall, say 60 ft long and I modeled it as (3) panels, each 20 ft long? The end zones should be at the ends of the 60' wall. Should I use option #3 but only at the joint at 0 ft and at 60 ft?
Thanks!
