← HistoryWhich construction risk increased when Mesopotamian ziggurats exceeded certain clay brick height thresholds?
A)Base sinking from unequal load distribution✓
B)Brick fracturing from rising damp salinity
C)Internal cracking from thermal expansion
D)Stair collapse from wind induced vibration
💡 Explanation
When ziggurats heights exceeded clay brick limitations, excessive compressive stress concentrated at the base because differing soil compaction under layers, triggering uneven settlement. Therefore sinking from load distribution resulted, rather than fracturing, cracking, or stair collapse requiring moisture ingress, thermal gradients, dynamic loads.
