← HistoryWhich consequence results when stacked, unreinforced Inca masonry walls exceed a slenderness ratio limits?
A)Foundation Coulomb stress decreases
B)Shear load toleration improves
C)Buckling instability risk increases✓
D)Material tensile strength increases
💡 Explanation
Buckling instability risk increases due to exceeding slenderness ratio limits in Inca masonry. Increased height exacerbates Euler buckling, because the critical buckling load is inversely proportional to the square of the effective length, therefore compression leads to instability earlier, rather than increased shear load tolerance.
