ANSI E1.21-2020
Entertainment Technology - Temporary Structures Used for Technical Production of Outdoor Entertainment Events
ANSI E1.21 covers temporary structures used for the technical production of outdoor entertainment events. Custom temporary structures supporting performance platforms are included in the scope of this document, but pre-engineered, manufactured, modular staging systems used as platforms for performance, independent of other temporary structures, are not within its scope. This document helps to ensure the structural reliability and safety of these structures, by setting required levels of design and performance parameters, and establishes a reasonable standard for care for their design and use.
