Rogers,

Why not!?

Analyse for both; and  you should detail according to the requirements of
the case that governs. In this way you would have taken good care of both
the forces.

Hope that helps.

Subject: Concrete Shear Wall Below Grade; In-Plane / Out-of-Plane Behavior

To all those informed concrete designers out there.....here's a question
for you........(an item of discussion & debate)

Deep, reinforced concrete basement shear wall which is also experiencing
out-of-plane loading from the soil.  Shear wall design indicates the
need for horizontal and vertical stirrups as well as flexural steel in
either end of the shear wall.  The vertical stirrups act as shear
reinforcement to resist the in-plane shear load.  Can these same
stirrups be used as flexural reinforcement for the out-of-plane loading
from the soil ?  Not addressed in the PCA Notes on ACI 318-99 and have
found nothing in three textbooks addressing the issue.

Thanks
Robert
