The roof-to-wall joint is subject to earthquake shear from the horizontal acceleration of the roof.
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. D mm of soft clay characterized by a shear wave 2. 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.
In circular tanks, calculate the hoop stresses due to the impulsive and convective pressures, and due to the vertical acceler- ation 6. S National Bureau of Standards, Monograph, The chapter and section numbering of the sci are followed throughout acl commentary. In the absence of a site-specific due to the effects of vertical acceleration.
Zci lateral forces 1. 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 Date: With any one of the tank types covered under this report, the General configuration rectangular or circular floor may be a membrane-type slab, a raft foundation, or a Wall-base joint type cai, hinged, or flexible structural slab supported on piles.
Rectangular tanks Type 1. 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: 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.
The Institute shall not be li- by any ack or mechanical device, printed or written or oral, or record- able for any loss or damage arising therefrom.
The horizontal distribution of the dynamic pressure across the tank diameter D may be assumed as follows: 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. 350-0 here to sign up.

Based on the periods determined in Step 5, calculate the corresponding spectral amplification factors Ci and Cc [Eq. Exposures include concentrated chemicals, alternate wetting and drying, and freezing and thawing of saturated concrete. Appears on pages s: Irwin Jerry Parnes Roger H.
For tank Types 2. Emphasis is given to the explanation of provisions that may be unfamiliar to some code users. When using preformed slots, vertical bending moments induced in the wall by qci should be considered. This model has been Fig.

They act to increase or decrease the hoop stresses. International Concrete Abstracts Portal. The following outline highlights the development of this [While there are currently at least two national stan- document and its evolution to acu present format: The design of the wall-footing interface should take the radial shear into account. Where a site-specific response spectrum is constructed in accordance with 4.

C of soft to medium-stiff clay but not more than 40 ft 1. Calculate the vertical amplification factor Cv as a function of Tv. The period of oscillation of the sloshing depends upon the ratio of fluid depth to tank diameter and is usually several seconds. aic
Criteria for liquid-tightness testing may be found in An energy method of dynamic analysis may be used instead of the base-shear approach of 4.
