This specification is a reference specification that the licensed design professional can make applicable to any construction project by citing it in the project specifications. The licensed design professional supplements the provisions of this reference specification as needed by designating or specifying individual project requirements. This specification covers cast-in-place, normal weight, high-strength concrete in structures that must be designed for moderate to high seismic applications. More specifically, this specification applies to structures: --Located in Seismic Zones 2, 3, or 4 defined by the Uniform Building Code; --Assigned to Seismic Performance Categories C, D, or E of the BOCA/National Building Code (1993 and subsequent editions) or the Standard Building Code (1994 or subsequent editions); or --Seismic Design Categories C, D, E or F of the International Building Code or the National Fire Protection Association (NFPA) 5000 Building Construction and Safety Code. Irrespective of seismic hazard, seismic performance, or design category, these requirements shall apply to normal weight, high-strength concrete in intermediate or special moment frames and intermediate or special structural walls.
