Which mechanism limited the construction height of Gothic cathedrals before introduction of iron reinforcements?

💡 Explanation

When building taller structures, the arch and vault construction generated significant lateral thrust, which without sufficient counteraction through buttressing, caused the walls to buckle outward. Therefore lateral thrust overwhelmed buttresses, rather than tensile failure, settling, or resonance, which require different structural weaknesses.
