ASCE 55-16-2016 Tensile Membrane Structures.pdf

1、ASCE STANDARDASCE/SEI55-16Tensile Membrane StructuresPrepared by the Tensile Membrane Structures Standards Committee of the Codes and Standards Activities Division of the Structural Engineering Institute of ASCEStandard ASCE/SEI 55-16 provides minimum criteria for the analysis, design, and performan

2、ce of membrane-covered cable and rigid member structures, collectively known as tensile membrane structures. It is applicable to both permanent and temporary structures. The requirements of this standard apply whether the tensile membrane structure is independent of or attached to another structure.

3、 ASCE/SEI 55-16 updates the previous edition (ASCE/SEI 55-10) and replaces Standard ASCE 17-96, Air-Supported Structures, thus placing those guidelines next to conventional tensile membrane structures and frame-covered membrane structures, all in a single standard.Tensile Membrane Structures will be

4、 valuable to engineers and practitioners involved in the design or construction of a wide variety of tensioned fabric structures.Civil EngineeringASCE STANDARD ASCE/SEI55-16TensileMembraneStructuresPUBLISHED BY THE AMERICAN SOCIETY OF CIVIL ENGINEERSLibrary of Congress Cataloging-in-Publication Data

8、rocess that has been accredited by the American National Standards Institute (ANSI). Accreditation by ANSI, a voluntary accreditation body representing public and private sector standards development organizations in the United States and abroad, signifies that the standards development process used

9、 by ASCE has met the ANSI requirements for openness, balance, consensus, and due process.

All such stan-dards are developed by a consensus standards process managedby the ASCE Cod

17、es and Standards Committee (CSC). Theconsensus process includes balloting by a balanced standardscommittee, and reviewing during a public comment period. Allstandards are updated or reafrmed by the same process everyve to ten years. Requests for formal interpretations shall beprocessed in accordance

18、 with Section 7 of ASCE Rules forStandards Committees, which are available at www.asce.org.Errata, addenda, supplements, and interpretations, if any, for thisstandard can also be found at www.asce.org.This standard has been prepared in accordance with recog-nized engineering principles and should no

19、t be used without theusers competent knowledge for a given application. The publi-cation of this standard by ASCE is not intended to warrant thatthe information contained therein is suitable for any general orspecic use, and ASCE takes no position respecting the validityof patent rights.
