The shears along the bottom and side joints, and the top joint 35-01 case of a roof- covered tank, shall correspond to the slab reactions.
Dynamic lateral forces 1. The chapter and section numbering of the code are followed throughout the commentary. This document provides directions to the designer of liquid- containing concrete structures for computing seismic forces that are to be applied to the particular structure.
Because the impulsive and convective 4. Doyle Bryant Mather John F. Compute the dynamic lateral forces [Eq. Thus it cannot present background details or suggestions for carrying out its requirements or intent.
Because ACI is written as a legal document, it may be adopted by reference in a general building code or in regulations governing the design and construction of environmental engineering concrete structures.
Calculate the vertical amplification factor Cv as a function of Tv. Factor Z Table 4 a represents the maximum effective peak ground acceleration for the site, while C is a period- dependent spectral-amplification factor.

The duration of the fluctuations is 10 to 15 s for 0. The radial shear attains its maximum value at points on the tank wall ori- ented 0 and degrees to the ground motion and should be determined using cylindrical shell theory and the tank dimensions.
In general, the wall-footing interface should have reinforce- ment designed to transmit these shears through the joint.

Wi moves with the tank walls as they respond to the ground shaking the 9. Select an importance factor I from Table 4 c and a soil profile coefficient S from Table 4 b. For a tank with a height-to-diameter ratio of 1: If uplift develops on the xci side, then anchor cables 35001 be provided.
Circular tanks Type 2. The International Concrete Abstracts Portal is an ACI led collaboration with leading technical organizations from within the international concrete industry and offers the most comprehensive collection of published concrete abstracts. In a pseudo-static analysis: Walls parallel to the direction of the earthquake force shall be analyzed as shear walls subjected to the in- plane forces computed in 5.
They act to increase or decrease the hoop stresses. Appears on pages s: Determine the seismic coefficient Z from the seismic zone map, Fig. When using preformed slots, vertical bending moments induced in the wall by shear should be considered.
The design of the wall-footing interface should take the radial shear into account. Walls perpendicular to the earthquake force and in the trailing half of the tank shall be loaded perpendicular to their plane dimension B by: Note that the damping of the sloshing water is small, approximately 0.
