ACI 349M

Abstract

This Code provides minimum requirements for design and construction of nuclear safety-related concrete structures and structural members for nuclear power generating stations. Safety-related structures and structural members subject to this standard are those concrete structures that support, house, or protect nuclear safety class systems or component parts of nuclear safety class systems. <br>Specifically excluded from this Code are those structures covered by "Code for Concrete Reactor Vessels and Containments," ASME Boiler and Pressure Vessel Code Section III, Division 2, and pertinent General Requirements (ACI 359). <br>This Code includes design and loading conditions that are unique to nuclear facilities, including shear design under biaxial tension conditions, consideration of thermal and seismic effects, and impact and impulsive loads. <br>For structural concrete, <em>f</em>_c&#8242; shall not be less than 17 MPa, unless otherwise specified. <br>This Code shall govern in all matters pertaining to design and construction of reinforced concrete structures, as defined in 1.1.1, except wherever this Code is in conflict with the specific provisions of the authority having jurisdiction (AHJ). <br>This Code shall govern in all matters pertaining to design, construction, and material properties wherever this Code is in conflict with requirements contained in other standards referenced in this Code. <br>For special structures, such as arches, tanks, reservoirs, bins and silos, blast-resistant structures, and chimneys, provisions of this Code shall govern where applicable. <br>Intentionally left blank. <br>Intentionally left blank. <br><em>Concrete on steel form deck</em> <br>Design and construction of structural concrete slabs cast on stay-in-place, noncomposite steel form deck are governed by this Code. <br>This Code does not govern the design of structural concrete slabs cast on stay-in-place, composite steel form deck. Concrete used in the construction of such slabs shall be governed by Chapters 1 through 7 of this Code, where applicable. <br><em>Special provisions for earthquake resistance&#8212;</em> Provisions of Chapter 21 shall be satisfied. See 21.2.1.
