Working Groups 
TensiNet has launched several Working Groups. Each Working Group focuses on a specific topic and is responsible for its operation. During the Management Board meeting (twice a year) each WG leader reports about objectives and progress.

WG analysis & materials 
Leader: Peter Gosling
Mission: The driver behind this WG is the linking together of testing and analysis, such that each are supportive and inform each other, rather than being considered independently as is generally the current practice. Several Round Robin exercises were launched. The WG is currently preparing a submission for a H2020 ETN.
Calls & Announcements: Round Robin exercise II  (http://tensinet2015.aware.be/files/Announcement___calls/NEW_CALL_ROUND_ROBIN_II_-1.pdf) and Round Robin exercise III (http://tensinet2015.aware.be/files/Announcement___calls/NEW_CALL_ROUND_ROBIN_III.pdf).

WG ETFE 
Leader: Rogier Houtman 
Mission:The aim of this WG is to write specific design recommendations for ETFE foil structures. Current design recommendations are compiled in the publication of Appendix A5 of the European Design Guide for Surface Tensile Structures. 
Parts of the content have been used for the ETFE part in the SaP report (see WG Specifications and Eurocode). Also a first proposal to combine the different design strategies mentioned in Appendix A5 is formulated and included in the SaP report.
Next steps are to gain support and common understanding of the industrial parties involved in the ETFE business to come to an applicable design approach that shall become part of the Eurocode for the Structural Design of Tensile Membrane Structures.
The Japanese code on ETFE foil is being reviewed and compared with the current Appendix A5.
Publication: Design recommendations for ETFE foil structures - Appendix A5 of European Design Guide for Surface Tensile Structures (2013)

WG FOUNDATION (NEW)
Leader: Peter Gosling
Mission: The aim of this WG is to promote tensile architecture. The Foundation will support young researchers, engineers, architects in an exchange research programme or internship within a specific task.
Announcement: New since the TensiNet – Cost Action TU 1303 symposium (26-28 October 2016, Newcastle University)

WG LCA 
Leaders: Jan Cremers & Carol Monticelli
Mission: The aim of this WG is to review the current status on membrane materials and typical membrane structures with regard to sustainability and LCA issues. The information should be used as a key evaluation criterion in the objectification of the discussion on membrane materials. This state of the art aims to demonstrate the advantages of Life Cycle Design strategy answering to the environmental sustainability, in the case of ultra-lightweight structures.
In the review, on the one hand, the research results about the eco-efficiency principles in the field of membrane architecture, based on the application of Life Cycle Assessment methodology to membrane structures, are being investigated. On the other hand, the needs and requirements of designers and builders of these kinds of architectures are prominent to transform the research results into a sustainable good practice.
The LCA approach aims to a transparent evaluation of the complex environmental impacts of products and processes involved. From the industry side, the stages such as obtaining the raw materials, production, processing and transport are verified as well as use, reuse and disposal if applicable. From the side of the designers a comparative LCA study is made between different types of alternative building systems, in order to guide the designer to the most appropriate and eco-efficient solution for a specific context and the expected performance of the project.
Calls & Announcements:
- Questionnaire Sustainability in collaboration with COST Action TU1303 (update_QUESTIONNAIRE_ COST ACTION NOVEL STRUCTURAL);
- Recall and re-invite companies (designers and producers) to be active in the WG LCA discussion for collecting primary data and stating the real needs to improve a good practice in the use of these construction elements.
Actions: On the need of harmonization of the research about the availability of LCA data for membranes and on the basis of the collected information, a first set of eco-design principles for membranes structures is discussed. Ideas of a new sustainable design guide are also discussed.

WG Pneumatic structures 
Leaders: Jean-Christophe Thomas
Mission: The aim of this WG is to promote Pneumatic Structures through the recommendation of best practise ‐ which will hopefully improve standards, reliability, reputation and open up new markets to this form of construction. It is the intention of the WG to publish in the near future the Design recommendations for pneumatic structures - Appendix A6 of European Design Guide for Surface Tensile Structures.

WG Specifications and EUROCODE 
Leader: Marijke Mollaert
Mission: The aim of this WG is to develop Technical Specifications for the Design of Membrane Structures. Finally the objective is to establish common standardised design procedures and provide a Eurocode for Membranes structures which is of utmost value to achieve a harmonized safety level.
The WG developed ‘best practice’ technical recommendations for the Design of Membrane Structures in the form of a ‘Science and Policy Report’ (SaP).
Within CEN/TC 250/WG 5, CEN/TC 248/WG 4, the TensiNet Association and COST Action TU1303, an international team of researchers, engineers, architects, material producers and manufacturers work on the Technical Specifications and provide background information in support of the implementation and development of a future Eurocode for the Structural Design of Tensile Membrane Structures. The Eurocode will not only assist and support the industry and engineering offices but will also encourage potential clients to choose these sustainable type of construction.
Publication: SaP-Report ‘Prospect for European guidance for the Structural Design of Tensile Membrane Structures'. This background document consists of three major parts: (a) general explanations giving scientific and technical background for the design of membrane structures, (b) state-of-the-art overview on existing national and European rules and recommendations on the design of membrane structures, and (c) proposals for European harmonized design rules, which could be part of the future Eurocode for Tensile Membrane Structures.

WG  Specifications GOOD PRACTICE (NEW)
Leader: Heidrun Bögner-Balz 
Mission: The aim of this WG is to establish a quality standard in the manner of “good practice rules”. Rules for each branch (Membrane Material Producer, Raw Material Producer, Membrane Manufacturer, Designers/ Engineers, Architects, Testing Laboratories) will be formulated as well as general rules for all involved parties. As soon as the rules have been formulated and agreed, a quality seal “We follow the standards of good practice approved by the TensiNet Association” will be established.

 

The TensiNet Working Groups collaborate closely with the corresponding Working Groups of the COST Action TU1303 Novel Structural Skins (2014-2017). http://www.novelstructuralskins.eu/
