Hi everyone,

My question is :

I have an existing RC wall with boundary RC columns and I am adding a new RC wall next to it for seismic strengthening purposes. I want to make these two walls as one integrated wall.

How can I find the shear force at the interface between the New wall and the existing wall? I am using dowel bars to connect the new wall to the existing wall.

Also, I am designing a new footing below the new RC wall which is also to be connected to the existing footing below the existing wall. How do i find what are the forces at the interface between the two footings?
 
The forces between the two walls depends on at least two things:
1. How the lateral load gets into each wall...i.e. are there forces coming down the wall into one wall and not the other?
2. The relative stiffness between the two walls based on the concrete strengths, wall thicknesses/lengths and the underlying foundation stiffnesses as well.
