Concrete Structures for Containment of Hazardous Materials. It is the function of the commentary to fill this need. But there’s not a whole lot else available.

/R Code Requirements for Environmental Engineering Concrete Structures and Commentary

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. In my mind the reviewers are applying this code to storm water detention vaults where the intent of the code is to control tanks containing sewage effluent or toxic chemical bearing water.

Where the approved standard defines acceptance criteria in terms of allowable stresses as opposed to strengthsthe design seismic forces obtained from acii appendix shall be reduced by a factor of 1. Type 2—Circular tanks Type 2. Errata are not included for collections or sets of documents such as the ACI Collection.


For tank Types 2.

Join your peers cods the Internet’s largest technical engineering professional community. For explanation, refer to Housner []. The minimum vertical steel is listed at. The technical committees responsible for ACI committee reports and standards strive to avoid ambiguities, omissions, and errors in these documents.

ACI does not make any representations with regard to health and safety issues and the use of this document. Note that the damping zci the sloshing water is small: Compute the vertical amplification factor Ct in accordance with Section 9.

This code presents new material as well as modified portions of the ACI M Building Code that are applicable to environmental engineering concrete structures. The quality and testing of materials used in the construction are covered by reference to wci appropriate standard specifications. All section, table, figure and equation references are to UBC except as otherwise indicated.

This affects slabs on-grade or structural slabs as well as walls that detain storm water.

Register now while it’s still free! Loadings include normal dead and live loads and vibrating equipment or 350-066 forces. The cost implication here is minimal if any.

The impulsive pressures are not impulses in the usual sense but are associated with inertia forces produced by accelerations of the walls of the container and are directly proportional to these accelerations.

Overturning moments—Compute overturning moments for the lateral loads described above using the procedures of Section 4. I don’t think it’s legitimate to use ACI for storm water detention. ACI Committee Reports, Guides, Standards, and Commentaries are intended for guidance in planning, designing, executing, and inspecting construction.


For circular tanks, first calculate the natural period of vibration of vertical liquid motion Tv Eq. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

ACI Seismic Design of Liquid-Containing | Roy Quesada –

Normally, this is smaller than the impulsive effect, but if there is not enough dead load, the tank will tend to uplift. It could also be argued that for walls that are exposed in this locale, considering the limited 24 hour detention time available of the water in the tank to saturate the concrete walls, and considering the fact that most of the major storms in this area that would highly charge the tanks do not coincide with the time of extended freezing conditions, the freezing of the aaci in a saturated state is highly unlikely.

Type 1—Rectangular tanks Type 1. Criteria for liquid-tightness testing may be found in This standard, however, does not cover the determination of seismic forces on the piles themselves.
