Accordingly, the basic scope, format, and environmental concrete structures. The general equation for base shear is also modified in Eq.

The following outline highlights the development of this [While there are currently at least two national stan- document and its evolution to the present format: Similarly, the terms in Eq.

The overturning moment exerted by h cosh [ 3. Prachand Paul Zoltanetzky Robert E. For tank Types 2. Atomic Energy Commission, References to much of the research data referred to in preparing the code are given for those who wish to study certain requirements in greater detail.

For 30-01 tank with a height-to-diameter ratio of 1: Superimposed on these lateral unbalanced forces shall be the axisymmetric lateral hydrodynamic force resulting from the hydrodynamic pressure phy acting on the tank wall.

Downward pressures on the neo- prene bearing pads of free base circular tanks caused by overturning moments should be considered.

The sloshing pressures on the tank walls result from the fluid motion associated with the For all tanks, wave oscillation. Using the frequency values determined in Steps 3 and 4, calculate the corresponding natural periods of vibration, Ti and Tc [Eq.

Chemical attack; coatings; concrete durability; concrete finishing fresh concrete ; concrete slabs, crack width, and spacing; cracking fracturing ; environmental engineering; inspection; joints junctions ; joint sealers; liquid; patching; permeability. Soil Profile D need not be assumed unless the building official determines that Soil Profile D may be present at the site, or in the event that Soil Profile D is established by geotechnical data.

Wi moves with the tank walls as they respond to the ground shaking the 9. In a pseudo-static analysis: It is the function of the commentary to fill this need.

The horizontal distribution of the dynamic pressure across the tank diameter D may be assumed as follows: D mm of soft clay characterized by a shear wave 2. The impulsive pres- pressure, EBP [Fig. Where a site-specific response spectrum is constructed in accordance with 4.

The duration of the fluctuations is 10 to 15 s for 0.

Kothe coefficient of lateral earth pressure at rest, shall be used in estimating the earth pressures, unless it is demonstrated by qci that the structure deflects sufficiently to lower the coefficient to some value between Ko and Ka, the active coefficient of lat- eral earth pressure. Calculate the hydrodynamic pressure phy using Eq.

Determine sci seismic coefficient Z from the seismic zone map, Fig. This document was replaced by In computing these pressures, recognition shall be made of the existence, or lack 30-01, of ground water table.

The code portion of this document covers the structural design, materials selection, and construction of environmental engineering concrete structures. This code presents new material as well as modified portions of the ACI Building Code that are applicable to environmental engineering concrete structures. Loadings include normal dead and live loads and vibrating equipment or hydrodynamic forces.

Welding of reinforcement is covered by reference to the appropriate AWS standard. Emphasis is given to the explanation of provisions that may be unfamiliar to some code users. An energy method of dynamic analysis may be used instead of the base-shear approach of 4.


Calculate the mass of the tank shell wall Ww, and roof Wr. 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.

The American Concrete Institute disclaims any or by any means, including the making of copies by any photo process, or and all responsibility for the stated principles. Factor Z Table 4 a represents the maximum effective peak ground acceleration for the site, while C is a period- dependent spectral-amplification factor.

In locations where the soil properties are not known in suffi- cient detail to determine the soil profile, Type C shall be used.

Where loss of liquid should be prevented for example, tanks for the storage of toxic liquidsor where overtopping may result in scouring of the foundation materials or cause dam- age to pipes, roof, or both, then one or more of the following measures should be undertaken: Early Jack Moll William C.

In the absence of a site-specific due to the effects of vertical acceleration.

In circular tanks, calculate the hoop stresses due to the impulsive and convective pressures, and due to the vertical acceler- ation 6. They act to aco or decrease the hoop stresses. If uplift develops on the heel side, then anchor cables must be provided. Doyle Bryant Mather John F. Irwin Jerry Parnes Roger H.
