EU set for new regulations for membrane structures

The European Union group responsible for structural Eurocodes has since 2010 been in preparation to publish Eurocode 12: ‘Tensile Surface Structures’, and in 2016 published a technical report ‘Report Eur 27716 EN’ in support of the drawing up of the final Eurocode.

Ezpagio Magazine recently published a summary on this report, including a breakdown of some the most influential information included. The introduction of the report includes the reasons why a Eurocode for membrane structures is necessary. It also covers the existing Eurocodes applicable to membrane structures; as well as the national regulations in Germany, Holland, France, Belgium and Spain.

General features of membrane structures which have been taken into consideration include shape, area, pre-stressing, capacity for deformation and manufacture. And further attention to detail has been given to materials, bases, durability, calculation basis, ultimate and service limit states and construction.

Development of membrane structures currently deals with possibilities of shape, efficiency, lightness and flexibility and sustainability. It is these unique characteristics that make tensile structures appealing to architects, and a sought after alternate to regular building models. Tensile Structures allow a great deal of light, can be used for waterproofing and are able to achieve alternative shapes adding to the aesthetics of a building. They can also improve thermal behaviour, control solar radiation, or capture solar energy.

The report hopes to be the basis for drawing up the ‘Membrane Structures’ Eurocode. The European Union group responsible will complete the codes based on testing regulations. The reference section includes 168 descriptions on which the document is based, and includes 52 projects carried our in Europe in the appendix.
