12. The COST Framework • What is funded by COST ? • Meetings, Workshops and Seminars (Travel expenses) • Short Term Scientific Missions (STSM) • Publications • Actions‘ Management • Research is not directly financed,but – communication and dissemination is facilitated ! The yearly budget per Action is around 90‘000 €

13. The COST Framework • How are the Actions initiated ? • A group of researchers has the vision of a new research network • The vision is formulated and the need is substantiated by writing a draft ‚Memorandum of Understanding‘ (MoU) • The draft MoU serves as a application document and is submitted • The MoU is reviewed and evaluated by several instances within the COST administration • In case of approval, the Action enters into force • Time perspective: First submission - approval: • 18 Month (E55) • 8 Month (new ‚OpenCall‘ system)

14. COST Action E55 - Modelling the Performance of Timber Structures • Status and Organization of the Action • Aim and Scope – the Memorandum of Understanding

15. General Information • The Action started at December 15, 2006 with its 1. Management Committee (MC) meeting. The duration of the Action is 4 years. • The Memorandum of Understanding is signed by 16 countries – 2 countries indicated the intention to sign (update 05/2007). Austria, Belgium, Croatia, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Portugal, Slovenia, Spain, Sweden, Switzerland, United Kingdom, Lithuania • The scientific work of the Action is organized by having 3 working groups.

16. Organization of the Action • The activities within the action are organized and directed by the MC. The MC consists of up to two delegated per country. • The MC delegated the responsibility for specific issues to the ‚steering committee‘.
