Base shear thru friction only?
Base shear thru friction only?
(OP)
Is it ever OK to rely ONLY on friction to resist base shear?
Specifically - precast load bearing wall panels providing the lateral force resisting system where the base shear is taken out in friction on plactic bearing strips? By my interpretation, ACI 16.5.1.4 says no.

RE: Base shear thru friction only?
Always, but always provide some steel to anchor your panel. Even if friction is sufficient by analysis, I would never specify a panel that didn't have at least nominal bars (say low grade 10mm dia at 600 crs) to the foundation.
All that aside, you'll have to wait for someone who applied the US codes to comment on your point regarding "16.5.1.4".
