- Abstract
- 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 obtained from three experimental programs. The results of the comparison show that predictions become less consistent with decreasing specimen strength and amount of reinforcement. Overall, predictions were within 20% of test results for 50% of the specimens. For unreinforced walls and walls in which no flexural reinforcement was used, predicted strength was less than half the measured 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 predictions with experimentally-measured ultimate strength can be improved significantly.
