Epic Engineering Failures and the Lessons They Teach
Summary
The 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. Explore what led to this tragedy, including problems with the most sophisticated engineering tool of all—human judgment.
