to produce either shear dominated or flexurally dominated response. A summary of Shing’s test results are shown in Table 3. Of Shing’s walls, specimens 1, 2, 10, 12 and 15 exhibited primarily flexural response (10 and 15 actually exhibited mixed response) and specimens 3,4, 5, 7, 9, 13, 14 and 16 exhibited shear response. Shing’s specimens 6, 8, and 11 exhibited significant base sliding and results for those walls are not included in this paper.

Eikanas tested seven reinforced concrete masonry walls. Aspect ratios varied from 1.0 to 2.63. Walls were reinforced both horizontally and vertically and the amount of reinforcement was varied from wall to wall. All of Eikanas’s walls exhibited primarily flexurally critical behavior. A summary of Eikanas’s test results are shown in Table 4.

Ibrahim tested five reinforced concrete masonry walls. The walls were all 55 in tall and aspect ratios varied from 0.467 to 1.00. Walls were reinforced both horizontally and vertically. All of Ibrahim’s walls exhibited shear critical behavior. A summary of Ibrahim’s test results are shown in Table 5.
