Calculations for the ductility capacity of unconfined concrete masonry shear walls developed in a previous paper are extended to cover the case of confined masonry shear walls. Design charts are presented which show that the available ductility will always be greater than three times the value for a corresponding unconfined wall. Recommendations to govern the required extent of confinement are made.
