Intentionally engineering structural weaknesses into a building can prevent catastrophic collapse. This counterintuitive strategy successfully limited damage to a two-storey concrete building in its first real-world experiment.

The innovation was inspired in part by the way lizards will sacrifice their tails to escape the clutches or jaws of predators.
