Overstrength factor for wall supporting planted column

[EngrRC]

I am designing a concrete wall which carries a transfer beam supporting a planted/floating column.

ASCE7 mentions the wall should be designed for seismic load with overstrength factor. Now, my question is does all the seismic load resisted by the wall (coming all the way up from uppermost level) need to be amplified? Or only that seismic load imparted by the transfer beam?

Clause 12.3.3.3 is for Elements Supporting Discontinuous Walls or Frames.

I am not sure if the planted column is gravity only column ..

Suggest you to look C12.3.3.3 and provide a descriptive sketch to get better responds..

The planted column is not part of the lateral resisting system. From the commentary you mentioned and the applicability limitations, I understand that overstrength need not be applied.

The Provisions don't specifically address this as far as I could find.

It seems logical that the amplification is appropriate for the transfer element and the connections. The concrete wall would be designed for the un-amplified forces except for those coming from the transfer element, whose forces remain amplified.
