This standard prescribes procedures for the seismicanalysis and design of liquid-containing concrete struc tures. These procedures address the “loading side” of350-01/ACI 350R-01 Chapter 21. seismic design and shall be used in accordance with ACI
should cover both aspects of seismic design: the “load-ing side" (namely the determination of the seismic loads based on the seismic zone of the site the speci-fied effective ground acceleration and the gemetry of the structure) and the “resistance side” (the detaileddesign of the structure in accordance with the provi-sions of the code so as to safely resist those loads). (b) To cstablish the scope of the new procedures consistentinclusion of all types of tanksrectangular as well as with the overall scope of ACI 350. This required thecircular; and reinforced concrete as well as prestressed.

INTRODUCTION
The following outline highlights the development of thisdocument and its evolution to the present format:
[While there are currently at least two national stan-analysis and design of liquid-containing structures dards that provide detailed procedures for the seismicprestressed concrete tanks only]. (References 17 and 18) these are limited to circular
From the time it embarked on the task of developing an “ACI318-dpendent”code Commitee 350 decided oexpand on and supplement Chapter 21 *Special Provi-sions for Seismic Design " in order to provide a set of thorough and prehensive procedures for the seismicanalysis and design of alltypes of liquid-containing environmental concrete structures. The mittee'sdecision was influenced by the recognition that liquid- containing structures are unique structures whose seis-national codes and standards. A scismic design sub- mittee was appointed with the charge to implementthe mittee's decision.
As the “loading side” of seismic design is outside the scope ofChapter 21 ACI 318 it was decided to maintain this practicein ACI 350 as well. Accordingly the basic soope format and mandatory language of Chapter 21 of ACI 318 were retainedtal engieinstrthisroacffeatleast with only enough revisions to adapt the chapter to environmen-oflimitingits seismicdeig prvisis to thersistan id vantages: (a) It allows ACI 350 to maintain ACI 318's practiceonly; and (b) it makes it easier to update these seismic provi-ments in the field of seismic hazard analysis and evaluation. -nondu pue suqp uanba atp pm dn daoy o se os suos
