ACI 318-08 Section 14.3.6
(OP)
Does anybody have an understanding of this provision? I am designing a Tilt-Up building and want to add as few stirrups as possible at my jaamb locations. The first part of this provison tells me to check the steel area against 1% of the gross concrete area for stirrup requirements. Are they talking about ANY vertical reinforcement, or just vertical reinforcement that is used as compression reinforcement? My tilt walls are controlled by flexural tension in the out-of-plane direction, and because of this the flexural steel is my vertical steel. Is the code really checking my stirrup requirements against my fexural reinforcement or am I reading it incorrectly? Any info help. Thanks.

You say "controlled" by flexure, but with any axial load, that pushes you into an axial/moment interaction (small as it may be) and you have to follow the rules on ties.

However this does not forfeit the need to check for shear accompanying flexure, either directly applied loads or through constraints.
