- S1 E12 - Stone Masonry: Beauvais CathedralJune 21, 202338minOn November 29, 1284, much of the Cathedral of Saint-Pierre at Beauvais collapsed without warning. Had this Gothic church simply exceeded the inherent maximum height of a stone structural system, as some historians have suggested? Watch fascinating demonstrations that both explain the function of the medieval flying buttress and point to the design flaws that most likely caused the collapse.Free trial of The Great Courses Signature Collection or buy
- S1 E13 - Experiment in Iron: The Ashtabula BridgeJune 21, 202339minHanding lucrative contracts to family members rarely has it led to such a public catastrophe as the 1876 Ashtabula Bridge disaster. As you learn the fascinating history of entrepreneur Amasa Stone—who built an iron bridge using a structural concept specifically developed for wood—you’ll follow the mistakes that led to America’s worst rail accident and worst bridge failure up to that time.Free trial of The Great Courses Signature Collection or buy
- S1 E14 - Shear in Concrete: The FIU Pedestrian BridgeJune 21, 202335minThe Florida International University Pedestrian Bridge was created with long-span trusses made of reinforced concrete, using post-tensioning to prevent cracking. Cracks that appeared were said to be “not a safety issue”—until a truss collapsed, killing six people.
