Figure 13~16 shows the comparison between two structures under the same boundary condition. The first model of the two has exactly the same pillars and the second model has different pillars in terms of width (ranging from 1 to 4). In both models, the bottom boundary is set to be fixed where no displacement is allowed and top boundaries have the same amount of displacement. What's interesting is that with the same amount of vertical strain, the thinner pillar in the second model did not show a higher tendency of yielding (or at least not visible under such loading condition).
