Episode Details

Ever looked around your apartment and wondered why hundreds of tons of furniture, people, and concrete don't just punch through the floor? This episode traces the hidden gravity load path — from the rebar in your floor slab, through beams and columns, into the foundation, and all the way down to the ground. We explore the elegant partnership between concrete and steel, the catastrophic consequences of cutting corners (including the 1995 Sampoong Department Store collapse), and the meticulous engineering that makes modern buildings possible. If you've ever stared at your ceiling and wondered what's holding it up, this one's for you.
