Which structural consequence occurred when medieval master builders miscalculated arch buttress placement in cathedrals?

💡 Explanation

When buttress placement was miscalculated, insufficient lateral support resulted from inadequate counter-thrust, leading to outward bulging of the nave walls due to the arch's horizontal force. Therefore wall bulging results, rather than roof collapse, foundation sinking, or weathering which involve different mechanisms and forces.
