A proposed equation for estimating the strength of
partially-grouted masonry shear walls failing in the
shear mode is used to compare predicted strengths with
the test results of 72 specimens from three experimental
programs. The comparison shows that the predictions
become less consistent with decreasing specimen strength
and amount of reinforcement. Overall, predictions were
within 20% of the test results for 50% of the specimens.
For unreinforced walls and walls which had no vertical
reinforcement, the predicted strength was less than half
the test strength. It is shown that by altering the
parametric functions in the predictive equation to
represent more closely post-cracking resistance
mechanisms in shear walls, the correlation of prediction
with measured strength can be improved significantly.
