The photo on the cover shows a view of the concrete canopy of the “Maison de l'Écriture” at Montricher, Switzerland (structural design: “Muttoni & Fernández, consulting engineers”). It is a complex structure combining ordinary reinforcement, post‐tensioning and steel fibres, and refined design methods were used for its analysis and design. For most structures, however, design can be performed on the basis of simpler design methods. The need for codes that offer sufficient flexibility to be used in an efficient manner for design of simple and complex structures can be satisfied by using codes based on a Levels‐of‐Approximation (LoA) approach. The LoA approach provides simple and physically‐grounded design expressions (sufficient for a large variety of cases) but whose mechanical parameters can be refined in successive levels when required (for design or for assessment of complex structures). A more in‐depth explanation of this approach is provided on pages 32–41 of this issue. (Photo: Rafael Rojas )
