Presently, about one-third of a ton of concrete is produced each

20、year for every human being in the world (some 2 billion tons per year).International Standards on concrete technology can play a significant role for improving the global trade climate. International Standards in the field of concrete and its use in civil infrastructure are ever more needed as the e

21、conomic development of the world continues.ISO/TC 71/SC 4 was established to develop standards for performance requirements of structural concrete. This International Standard gives the performance and assessment requirements for design standards on concrete structures. It is an umbrella-type docume

22、nt with general provisions and guidelines intended to provide wide latitude of choice in terms of general requirements for performance and assessment of concrete structures. It should be used, therefore, in conjunction with sound engineering judgment.National and regional standards are generally mor

23、e prescriptive in nature than International Standards and vary somewhat from region to region.In a document accessible at http:/isotc.iso.org/livelink/livelink/Open/ISO_19338, ISO/TC 71/SC 4 has defined a procedure to assess whether a national or regional standard can be deemed to satisfy this Inter

24、national Standard. This separate document also gives the list of national and regional standards that so far have gone through the procedure and are deemed to satisfy this International Standard.

25、for design standards on structural concrete1 ScopeThis International Standard provides performance and assessment requirements for design standards of structural concrete. It can be used for international harmonization of design and construction requirements.This International Standard includesa) re

26、quirements, which define the required structural concrete performance,b) criteria, which give means for expressing the requirements, andc) assessment clauses, which give acceptable methods of verifying the specific criteria.2 Normative referencesThe following documents, in whole or in part, are norm
