COST Action E24 Objectives: General: specifications for a level 1 PMC, including methods and case studies For each topic: Organisation into sub-chapters Justification of assumptions Description of methods Proposal of case studies Distribution of tasks Dissemination: book, CD, Demonstration tools …

4. COST Action E24 Level 1 probabilistic model code Summary of Zürich conclusions Level of sophistication: RV discretisation, time invariant models Short term strength: LN tail fitting for timber and EWP, correlation models (other properties than bending strength) DOL: time invariant probabilistic formulation Size effects: parametric equation based height/length effects on material strength and stiffness System effects: discretisation into components arranged in logical systems (e.g. serial /parallel). Linearisation and iterative processes.
