Hi,
using
the linear stress method
sigma(max)=N/S +(M*v/I) .
sigma(min)=N/S -(M*v/I) .
I :inertia of the wall
S:area
M:moment
v:dist between GC to left boundary
by increasing area and inertia of the shear wall / additional webs (stiffeners)/ between boundary zones (upstream to downstream) the stress will be reduced.
the positions of these webs depends geometric arrangement of the structure...
ACI 318-02 gives another method
