13、y the Society. All such standards are developed by a consensus standards process managed by the Society s Codes and Standards Committee (CSC). The consensus process includes balloting by a balanced standards committee made up of Society members and nonmembers, balloting by the membership of the Soci

14、ety as a whole, and balloting by the public. All standards are updated or reaffi rmed by the same process at intervals not exceeding fi ve years.

Earlier drafts of this Standard and Commentary were reviewed and balloted several times by the full Standards Committee. The votes and comments returned by

32、the members were reviewed and their proposed resolutions developed by the appropriate subcommittees. The result-ing approved changes in the text are included in this volume. Some of the provisions were adopted from other codes, standards, regulations, and specifi cations; some refl ect pre-vailing i

Preparation of a standard for Design Loads

34、 on Struc-tures during Construction and its outline were originally proposed to ASCE by Robert T. Ratay in 1987, resulting in the fi rst edition of the Standard published in 2002 as ASCE/SEI 37-02, Design Loads on Structures during Con-struction . The Committee, through its subcommittees, has been w

35、orking on the development of a revision to the Standard to embrace comments, recommendations, and experiences since the original 2002 edition, and to supple-ment the loading requirements of ASCE/SEI 7-10 , Minimum Design Loads for Buildings and Other Structures , since the latter does not include re

36、quirements for loads during con-struction. The environmental loads provisions of this ASCE/SEI 37-14 have been aligned with those of ASCE/SEI 7-10 and adjusted for the duration of the construction period. Final committee balloting was completed, and public comments solicited and resolved in mid-2014
