Seismic Design of Liquid-Containing Concrete Structures and Commentary (ACI 350.3-06)

Description

his standard is a companion standard to Chapter 21 of the American Concrete Institute, “Code Requirements for Environ-mental Engineering Concrete Structures and Commentary (ACI350-06)” (ACI Committee 350 2006).This standard provides directions to the designer of liquid-containing concrete structures for computing seismic forces that are to be applied to the particular structure.

The designer should also consider the effects of seismic forces on components outside the scope of this standard, such as piping, equipment (for example, clarifier mechanisms), and connecting walkways where vertical or horizontal movements between adjoining structures or surrounding backfill could adversely influence the ability of the structure to function properly (National Science Foundation 1981). Moreover, seismic forces applied at the interface of piping or walk ways with the structure may also introduce appreciable flexural or shear stresses at these connections.
