ACI 349

Abstract

This Code provides the minimum requirements for the design and construction of nuclear safety related concrete structures and structural elements for nuclear power generating stations. Safety related structures and structural elements subject to this standard are those concrete structures which 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 Standard 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> This Code shall govern in all matters pertaining to design and construction of reinforced-concrete structures, as defined in 1.1.1, except where the Code is in conflict with the specific provisions of the regulatory or jurisdictional authorities. <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> This Code does not govern design and installation of portions of concrete piles and drilled piers embedded in ground. <br> This Code does not govern design and construction of soil-supported slabs, unless the slab transmits vertical loads from other portions of the structure to the soil. <br> Concrete on steel form deck <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 Parts 1, 2, and 3 of this Code, where applicable. <br> Special provisions for earthquake resistance - Provisions of Chapter 21 shall be satisfied. See 21.2.1.
