PCI-124-18 The Precast/Prestressed Concrete Institute (PCI) first issued a manual for the design for fire resistance of precast/prestressed concrete in 1977. A second edition was prepared in 1989 and a third edition in 2011. The recommended design procedures in those three editions were based on fire test data and reports for precast/prestressed concrete dating back to the 1960s. Little has changed since then in fundamental design for fire resistance. While fire resistance is discussed in other publications as "calculated" fire resis- tance, those provisions have generally been prescriptive. That is, tables of information are used to select concrete mass or protection for steel. Since the first edition of the PCI manual, rational design, which is truly a fire resistance calculation procedure, has been demonstrated. Though not a standard, the first edi- tion of the International Building Code in 2000 referenced the procedures in the PCI fire design manual as being acceptable for prestressed concrete slabs not covered elsewhere.With the 2014 designation of PCI as an ANSI (American National Standards Institute) Accredited Stan- dards Developer, the material for fire resistance of precast and precast, prestressed concrete was deemed important enough to the precast concrete industry that the newest edition of the provisions would be developed in a consensus standard form. Thus, the design procedures would be referenced in the 2021 International Building Code as a standard developed through an ANSI consensus process.
