The dynamic properties, including periods of vibration and lateral coefficients, shall be permitted to be deter- mined on the basis of generally acceptable methods of dynamic analysis. Typical structures include conveyance, storage, and treatment structures. The site factor shall be established from properly substantiated geo- technical data.

This document was replaced by Typically, the distribution of forces and wall reactions in circular tanks will be similar to that shown in Fig. For tank Types 2.
The sloshing pressures on the tank walls result from the fluid motion associated with the For all tanks, wave oscillation. Compute the vertical distribution of the impulsive and convective force components in accordance with Chapter 5.
In rectangular tanks, calculate the stresses in the wall due to the impulsive and convective pressures, depending on the structural system considered 6. The chapter and section numbering of the code are followed throughout the commentary. Circular tanks Type 2.
Calculate the vertical amplification factor Cv as a function of Tv. If uplift develops on the heel side, then anchor cables must be provided.
In general, the wall-footing interface should have reinforce- ment designed to transmit these shears through the joint. Calculate the mass of the tank shell wall Ww, and roof Wr. Walls parallel to the direction of the earthquake force shall be analyzed as shear walls subjected to the in- plane forces computed in 5. However, a newer version of this document exists.
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. 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.
Such structures are used for conveying, storing, or treating liquid, wastewater, or other 350-0, such as solid waste. Among the subjects covered are: Walls parallel to the direction of the earthquake force shall be loaded in their plane dimension L by: This code presents new material as well as modified qci of the ACI Building Code that are applicable to environmental engineering concrete structures.
Calculate the bending and overturning moments [Eq. It is the function of the commentary to fill this need. Log In Sign Up. Because the impulsive and convective 4. International Concrete Abstracts Portal. Welding of reinforcement is covered by reference to the appropriate AWS standard. If friction between the wall base and the footing, or between the wall base and the bearing pads, is insufficient wci resist the avi shear, some form of mechanical restraint such as dowels, galva- nized steel cables, or preformed slots may be required.
/R Code Requirements for Environmental Engineering Concrete Structures and Commentary
The general equation for base shear is also modified in Eq. Superimposed on these lateral unbalanced forces shall be the axisymmetric lateral hydrodynamic force resulting from the hydrodynamic pressure phy acting on the tank wall. Atomic Energy Commission, The overturning moment exerted by h cosh [ 3.
Select an importance factor I from Table 4 c and a soil profile coefficient S from Table 4 b. Remember me on this computer. The designer should also consider the aco 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.
S National Bureau of Standards, Monograph, Wi moves with the tank walls as they respond to the ground shaking the 9. Help Center Find new research papers in: The maximum reaction force will be given by: Select the factor Rw specified for the class of structure being investigated Table 4 d. 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.
