Full Description

This standard describes current recommended practice for the design, construction, inspection, and maintenance of wire- and strand-wound, circular, prestressed concrete water-containing structures with the following four types of core walls:

1) Type Icast-in-place concrete with vertical prestressed reinforcement
2) Type IIshotcrete with a steel diaphragm
3) Type IVcast-in-place concrete with a steel diaphragm

This edition reflects current thinking and construction practices, and changes include but are not limited to

1)References to ACI 350, Code Requirements for Environmental Engineering Concrete Structures
2) The addition of specific strength requirements for concrete slab
3) "Portland cement" is now referred to as "cementitious material"
4) The addition of "urethane elastomer" as a type of sealant and joint filler
5) An update to the minimum design wind and seismic loads
6) The addition of construction loads as a roof design load
7) A reduction of the minimum roof rise-to-span ratio
8) The addition of requirements for compaction of cohesionless base material, such as gravel, under the floor
9) Guidance on conditions where an interior ladder and/or wall accessway would be appropriate
11) Incorporation of the new seismic design approach based on the IBC, ASCE 7-05 code standards and current seismic technological advances
12) The inclusion of urethane as a suitable material for crack injection
