Lessons from Structural Analysis of a Great Gothic Cathedral: Canterbury Cathedral as a Case Study

A structural analysis of Canterbury Cathedral, a UNESCO World Heritage Site and one of the UK's most iconic Gothic cathedrals, reveals that its damage patterns—characterized by repetitive cracks on vault intradoses and outward rotating movements in buttresses—stem from both extreme events and long-term processes. Using ambient vibration tests and finite element (FE) modeling, researchers calibrated a digital representation of the cathedral’s transverse section to match observed deformations. Nonlinear static analyses identified key factors influencing structural integrity, including construction history, infill volume, lateral thrusts, and differential settlements. The validated model confirmed that current safety factors for lateral and vertical loading align with local hazards, while comparisons with limit analysis provided additional insights into the cathedral’s resilience. This study offers a method for assessing similar heritage structures, balancing preservation needs with structural stability.
