CEN TC 250 WG5 Membrane Structures, with the support of TU1303 WG5, established

the Scientific and Policy Report (SaP‐Report)

state‐of‐the‐art overview

design rules for membrane structures

(different approaches)



Available on the TensiNet website

There is a modification in the procedure of publication of CEN TC250 pre‐normative material:

1. First distribute the document without covers and no names of editors to CEN TC250, and to JRC (Joint Research Centre) for opinion.

2. Send the consolidated version to JRC for editing, covers and publishing.

CEN TC250 meeting in Naples,

17‐18 September

Future steps to establish the Technical

Specifications:

‐ Work on specific sections in the meetings + written report containing the main decisions

‐ Appoint a responsible person per specific section

‐ Case studies?

Round Table session

During the meeting in Denkendorf we discussed the need to raise awareness for the Eurocode.

It was decided to organize an event to inform engineers about what is going on. This could improve the involvement of the industry into the writing of the Technical Specifications (next phase after the SaP Report)

Round Table session

The idea is to invite a European group to discuss about the importance of our work for the Eurocode. Each country selects the 2‐3 important architects and/or engineers.Not a symposium, but a Round Table Session with an open discussion. Location: Frankfurt/Berlin/Paris/… (arrive in the morning, leave in the afternoon)

Guidance/educational pack: to be ready for dissemination at the Symposium + version available on the websiteFrom the report:‐ Make power‐point slides and background explanations. Who? ‐ Facts for the Engineers to design simple structures. ‐ Bring potential of fabrics to experts not knowing the technology, to inform them and give

them confidence in designing new structural typologies.

Tim Ibell at IASS2015


Guidance/educational pack: to be ready for dissemination at the Symposium + version available on the websiteFrom the report:‐ Make a book with drawings and photos where you flip through and get in touch with the

concepts‐ Nothing formally written or typed, but sketches, impressions, for dummies (simple

explanations)‐ Kits to make Tensioned Structures for interested people and kids (like the cardboard models

of famous buildings) + book explaining the structures
