从八十年代开始，国外提出了 “以性能为基础的消防安全设计”新概念，并开始对传统的“指令性”（或称“处方式”）建筑防火规范体系进行改革，着手建立性能为基础的防火规范（简称“性能化规范”）。性能化的消防安全设计是建立在消防安全工程学这一新兴科学的理论和应用技术 Since the 1980s, a new concept of “performance-based fire safety design” has been proposed in foreign countries. At the same time, it has begun to reform the traditional “mandatory” (or “prescription”) building fire protection system and set out to establish a Basic fire protection specifications (referred to as “performance specifications”). Performance-based fire safety design is based on the emerging science of fire safety engineering theory and application of technology
