← HistoryWhich consequence would arise with improper Inca ashlar masonry at Sacsayhuamán?
A)Increased seismic structural instability✓
B)Reduced thermal mass equilibrium
C)Accelerated alkalaic-silica reaction
D)Decreased material stress distribution
💡 Explanation
Increased seismic instability occurs through the mechanism of decreased joint friction, because precisely fitted stones resist slippage during earthquakes. Without this construction, the wall deforms excessively, therefore seismic resistance fails, rather than thermal or chemical effects arising.
