Design aids for EC2: design of concrete structures: design aids for ENV 1992-1-1, Eurocode 2, part 1

The Concrete Societies of The UK The Netherlands and Germany041921190X, 9780419211907

Eurocode 2 is the key document for future structural design in concrete throughout Europe. To use the Code effectively, structural engineers need a range of aids in the form of flow charts, design charts and simplified procedures. This book provides all of these, and is written with the authority of collaborative work by members of the Concrete Societies of the UK, the Netherlands and Germany. The preparation of the book has been funded under the SPRINT European Community programme for innovation and technology transfer.
