(ACI ) An ACI Standard. Reported by ACI Committee Seismic Design of Liquid-Containing Concrete Structures and Commentary. ACI Seismic Design of Liquid-Containing Concrete Structures and Commentary. standard by American Concrete Institute, 01/01/. The seismic design provisions of the previous () edition of ACI were very limited in ACI covers all types of concrete tanks (prestressed and.

The user should note the following general design methods used in this standard, which represent some of the key differences relative to traditional methodologies, such as those described in ASCE The full and complete returned product will be accepted if returned within 60 days of receipt and in salable condition.
To produce a self-contained set of procedures that would enable a practicing engineer to perform a full seismic analysis and design of a liquid-containing structure. To establish the scope of the new procedures consistent with the overall scope of ACI This approach offers at least two advantages:.
– ACI Seismic Loads for Liquid-Containing Rectangular RC Tank
These items are not eligible for return. For a listing of and access to all product errata, visit the Errata page. Choose Product Language English. The seismic force levels and R-factors included in this standard provide results at 30.3-06 levels, such as those 350.-06 for seismic design in the International Building Code IBCparticularly the applicable connection provisions of IBC.
This standard prescribes procedures for the seismic analysis and design of liquid-containing concrete structures.
Seismic Design of Liquid-Containing Concrete Structures and Commentary
As the loading side of seismic design is outside the scope of ACIChapter 21, it was decided to maintain this practice in ACI as well. This meant that these procedures should cover both aspects of seismic design: Any applicable errata are included with individual documents at the time of purchase.
This required the inclusion of all types of tanks—rectangular, as well as circular; and reinforced concrete, as well as prestressed. The following paragraphs highlight the development of this standard and its evolution to the cai format:.
It makes it easier to update these seismic provisions so as to keep up with the frequent qci and improvements in the field of seismic hazard analysis and evaluation.
ACI 350.3-06 Seismic Design of Liquid Containing Concrete Structures and Commentary
Rather than combining impulsive and convective modes by algebraic sum, this standard combines these modes by square-root-sum-of-the-squares.
These procedures address 305.3-06 loading side of seismic design and are intended to complement ACISection 1.
Instead of assuming a rigid tank for which the acceleration is equal to the ground acceleration at all locations, this standard assumes amplification of response due to natural frequency of the tank. Provisions similar to Section 1.
350.3-06 Seismic Design of Liquid-Containing Concrete Structures and Commentary
Accordingly, the basic scope, format, and mandatory language of Acj 21 of ACI were retained with only enough revisions to adapt the chapter to environmental engineering structures. Errata are not included for collections or sets of documents such as the ACI Collection. Concrete Structures for Containment of Hazardous Materials.
