A structural system using a diagonal grid of steel or concrete members that provides both vertical support and lateral stability for tall buildings. This creates an efficient structural framework while eliminating the need for separate bracing systems.
Portmanteau of 'diagonal' and 'grid,' coined in the early 2000s as this structural system gained popularity in skyscraper design. The concept evolved from traditional braced frame structures but with the diagonal elements integrated into the building's skin.
