Abstract
Partially grouted masonry shear walls are common structural systems in North America. This research examines the shear behavior of six partially grouted masonry shear walls. The walls ha an aspect ratio of 0.58, vertical reinforcement ratio of 0.33% and axial force of 11 kips (49 kN). They were subjected to in-plane lateral cyclic loading in a displacement control. The walls had grout horizontal spacing of 24, 32, and 48 in. (610, 813, and 1219 mm, respectively). Horizontal reinforcement ratios ranging from 0.127% to 0.254% were investigated as well. The test results showed that the shear strength of the walls significantly depends on the grout horizontal spacing. In addition, there seems to be a threshold horizontal reinforcement ratio beyond which any increase in the reinforcement ratio does not result in increase in the shear strength of partially grouted shear walls. The measured shear strengths of the test specimens were compared to the predicted shear strength using MSJC (2008) shear design equations. The comparisons showed that the MSJC overestimated the shear strength of partially grouted walls having grout horizontal spacing greater than 24 in. (610 mm). Finally, strut and tie models analysis were developed and were able to predict the shear strengths of the walls within ±20%.
