Steel truss bridges are a common sight on roads and railways around the world, with many dating back to the late 19th and early 20th centuries. Despite their high strength-to-weight ratio, which allows them to support heavy loads, they are vulnerable to collapse. Some fail when one component breaks, while others remain standing. This puzzling difference has long been a mystery, but a new study has finally come up with an explanation.
Why some steel truss bridges stay standing after potentially catastrophic failure
