PCI-124-18是通过ANSI认可的共识程序开发的第一个PCI标准。它规定了用于耐火和提供防火保护的预制和预制预应力混凝土构件的设计要求。在本标准中，“预制混凝土构件”是指用非预应力变形钢筋或预应力钢绞线的任何组合加固的工厂浇筑混凝土构件。本标准提供了确定预制混凝土结构构件耐火性的可接受方法，包括墙、楼板和屋顶板、梁和柱。在应用这些设计方法时，应使用ASTM E119中的火灾暴露和适用终点标准。

PCI-124-18 is the first PCI standard developed through an ANSI-accredited consensus process. It specifies requirements for the design of precast and precast, prestressed concrete elements to resist fire and provide fire protection. For the purposes of this standard, "precast concrete element" shall mean a plant-cast concrete member reinforced with any combination of nonprestressed deformed reinforcement or prestressed strand. This standard provides acceptable methods to determine the fire resistance of precast concrete structural elements, including walls, floor and roof slabs, beams, and columns. The fire exposure and applicable end-point criteria of ASTM E119 shall be used in the application of these methods for design.
