Designing for the Crowd: How Stadiums Safely Hold Thousands

Modern stadiums are marvels of structural engineering, designed to accommodate tens of thousands of people while remaining safe, efficient, and responsive to the unexpected. This video explores how engineers plan for enormous static and dynamic loads, from the weight of the structure itself to the shifting movement of cheering crowds. We examine the complex systems of supports, cantilevers, and foundations that allow stadiums to remain stable under pressure, as well as the importance of redundancy in large-scale structural design. Beyond the visible architecture, we uncover how hidden engineering choices shape everything from how the seats are arranged to how fast an entire section can be evacuated during an emergency.

The video also investigates the resilience of stadiums against external forces such as wind and earthquakes, and the conseq ...
