Working Group 8: Metal Spatial Structures

Mission

Encourage and organize presentations, reports and publications on projects, designs and research related to Metal Spatial Structures.

Background

Working Group 8 was first organized as a WG of Spatial Steel Structures with Professor Yoshikatsu Tsuboi as the Chair in 1970s, then expanded by Professor Mamoru Kawaguchi to a WG of Metal Spatial Structures. They have published  Analysis, Design and Realization of Space Frames in 1979 as a draft, then published in the IASS Journal (IASS, Madrid, 1985, 114 pp.). After chaired by Professor Shiro Kato, its activities have been casted intensively on buckling and dynamic responses of metal spatial structures. In 2017, WG 8 has completed a publication "Guide to Buckling Load Evaluation of Metal Reticulated Roof Structures" which is now available on IASS web-site at Further Information for IASS Members. From 2018, a new chair Toru Takeuchi together with Su-Duo Xue (Vice-chair) and Shiro Kato (Vice-chair) are actively developing an international collaboration with a keen focus on buckling, earthquake responses and design methods of metal spatial structures including grid shells. 

Current Objectives

The objective of WG No. 8 is to develop and publish structural guidelines for design and construction of metal spatial structures.  At present WG No. 8 is focusing on two principal design concerns: "Buckling" and "Earthquake Response."  For both foci, WG No. 8 works from the following two aspects:
  • Aspect A: Organize sessions at IASS Symposia to promote discussions and exchange information among IASS members
  • Aspect B: Publish State-of-Art Reports on Metal Spatial Structures.

A special study group within the WG is concentrating on the dynamic behavior, including the earthquake response.  More recently, a new Working Committee has been organized to draft a Guide to Earthquake Response Evaluation of Metal Reticulated Roof Structures.

Membership

The current members listed below are all members of the IASS. The WG is eager to add members from all parts of the world.  Discussions continue for publication of state-of-the art papers and for preparation of the drafts of the structural guides.  IASS members who are interested in these activities are welcome to join; please contact one of the Co-Chairs.

  • Prof. Toru TAKEUCHI (Chair) - Japan
  • Prof. Dr. Su-Duo XUE (Co-Chair) - China
  • Prof. Dr. Shiro KATO (Co-Chair) - Japan
