Circular tanks Type 2. For partially buried tanks, the Rwi value may be linearly A soil profile containing more than 20 ft mm interpolated between that shown for tanks on grade, and for buried tanks. The commentary discusses some of the considerations of the committee in developing the ACI Code, and its relationship with ACI D mm of soft clay characterized by a shear wave 2. Emphasis is given to the explanation of provisions that may be unfamiliar to some code users.

If uplift develops on the heel side, then anchor cables must be provided. In a pseudo-static analysis: 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.

The designer should also consider the effects of seismic forces on compo- nents outside the scope of this document, such as piping, equipment for example, clarifier mechanismsand connect- ing walkways, where vertical or horizontal movements between adjoining structures or surrounding backfill could adversely influence the ability of the structure to function properly. Walls parallel to the direction of the earthquake force shall be loaded in their plane dimension L by: An energy method of dynamic analysis may be used instead of the base-shear approach of 4.

The maximum reaction force will be given by: It is the function of the commentary to fill this need. Enter the email address you signed up with and we’ll email you a reset link. The shears along the bottom and side joints, and the top joint in case of a roof- covered tank, shall correspond to the slab reactions. Bending moment on the entire tank cross section just above the base of the tank wall EBP: The code portion of this document covers the structural design, materials selection, and construction of environmental engineering concrete structures.


The amount of freeboard required for design will vary. Calculate the natural period of vibration of vertical liquid motion Tv.

/R Code Requirements for Environmental Engineering Concrete Structures and Commentary

Calculate the vertical amplification factor Cv as a function of Tv. In this model, Wi represents the resultant effect of the impulsive W tanh [ 0.

Exposures include concentrated chemicals, alternate wetting and drying, and freezing and thawing acu saturated wci. Such structures are used for conveying, storing, or treating liquid, wastewater, or other materials, such as solid waste. Where overtopping is tolerable, no freeboard provision is necessary. The Institute shall not be li- by any electronic or mechanical device, printed or written or oral, or record- able for any loss or damage arising therefrom.

Welding of reinforcement is covered by reference to the appropriate 305-01 standard. Equations and are adapted from Reference The general equation for base shear is also modified in Eq. The roof-to-wall joint is subject to earthquake shear from the horizontal acceleration of the roof. The site factor shall be established from properly substantiated geo- technical data.

They act to increase or decrease the hoop stresses. Serviceability requirements include liquid-tightness or gas-tightness. When using preformed slots, vertical bending moments induced in the wall by shear should be considered.

In circular tanks, calculate the hoop stresses due to the impulsive and convective pressures, and due to the vertical acceler- ation 6. Remember me on this computer. Calculate the effective mass of the impulsive component of the stored liquid Wiand the convective component Wcusing Fig.

In computing these pressures, recognition shall be made of the existence, or lack thereof, of ground water table. Skip to main content. Proper design, materials, and construction of environmental engineering concrete structures are required to produce serviceable concrete that is dense, durable, nearly impermeable, resistant to chemicals, with limited deflections and cracking. Calculate the mass of the tank shell wall Ww, and roof Wr. International Concrete Abstracts Portal. For tanks with roof overhangs, the concrete lip can be designed to withstand the earthquake force.


The quality and testing of materials used in the construction are covered by reference to the appropriate standard specifications. Failure to provide a means for shear transfer around the cir- cumference may result in sliding of the wall. In rectangular tanks, calculate the stresses in the wall due to the impulsive and convective pressures, depending on the structural system considered 6.

The sloshing pressures on the tank walls result from the fluid motion associated with the For all tanks, wave ai. Determine the seismic coefficient Z from the seismic zone map, Fig.

Similarly, the terms in Eq. Typical earthquake force distributions in slab action 5.
