Accoya structural design guide to Eurocode 5. (2012)
Report
Lawrence, A., Marcroft, J., Crawford, D., & Hairstans, R. (2012). Accoya structural design guide to Eurocode 5. Edinburgh, Scotland: Accsys Technologies

Until now, using wood in damp external conditions for structural applications has been a real challenge, chiefly because of the risk of fungal attack. The most effective preservatives are by definition toxic and so have environmental issues both in u... Read More about Accoya structural design guide to Eurocode 5..
