Concrete Structures for Containment of Hazardous Materials. Choose Product Language English.
This meant that these procedures should cover both aspects of seismic design: The following paragraphs highlight the development of this standard and its evolution to the present format:. Acu the loading side of seismic design is outside the scope of ACIChapter 21, it was decided to maintain this practice in ACI as well.
350.3-06 Seismic Design of Liquid-Containing Concrete Structures and Commentary
Any applicable errata are included with individual documents at the time of purchase. 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.
Rather than combining impulsive and convective modes by algebraic sum, this standard combines these modes by square-root-sum-of-the-squares. The user should note aaci 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.
These items are not eligible for return. Errata are not included for collections or sets of documents such as the ACI Collection.
– ACI Seismic Loads for Liquid-Containing Rectangular RC Tank
Accordingly, the basic scope, format, and mandatory language of Chapter 21 of ACI were retained with only enough revisions to adapt the chapter to environmental engineering structures. To establish the scope of the new procedures consistent with the overall scope of ACI This standard prescribes procedures for the seismic analysis and design of liquid-containing concrete structures.
It makes it easier to update these seismic provisions so as to keep up with the frequent changes and improvements in the field of seismic hazard analysis and evaluation. 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.
Seismic Design of Liquid-Containing Concrete Structures and Commentary
This required the inclusion acii all types of tanks—rectangular, as well as circular; and reinforced concrete, as well as prestressed. Provisions similar to Section 1. This approach offers at least two advantages:. The seismic force levels and R-factors included in this standard provide results at strength levels, such as those included for seismic design in the International Building Code IBCparticularly the applicable connection provisions of IBC.
These procedures address the loading side of seismic design and 35.3-06 intended to complement ACISection 1. For a listing of and access to all product errata, visit the Errata page.
