Background of the Eurocode programme In 1975, the Commission of the European Community
23、decided on an action programme in the field of construction, based on article 95 of the Treaty. The objective of the programme was the elimination of technical obstacles to trade and the harmonisation of technical specifications. Within this action programme, the Commission took the initiative to es

For fifteen years, the Commission, with the help of a Steering Committee wi
