← HistoryWhich risk increased during ziggurat construction from unbaked bricks?
A)Foundation subsidence via plastic deformation✓
B)Seismic amplification impacting structural stability
C)Differential salt weathering of facade
D)Increased wind load via Bernoulli effect
💡 Explanation
Foundation subsidence risk increases via plastic deformation because the compressive load from ziggurat weight exceeds the clay's yield strength, therefore causing downwards displacement rather than elastic deformation under the loads, if proper soil compaction was not undertaken.
