Introduction to the seventh edition In 2010 the then current European national standards for building and construction were replaced by the EN Eurocodes, a set of pan-European model building codes developed by the European Committee for Standardization. The Eurocodes are a series of 10 European Standards (EN 1990 – EN 1999) that provide a common approach for the design of buildings, other civil engineering works and construction products.
Introduction to the seventh edition In 2010 the then current European national standards for building and construction were replaced by the EN Eurocodes, a set of pan-European model building codes developed by the European Committee for Standardization. The Eurocodes are a series of 10 European Standards (EN 1990 – EN 1999) that provide a common approach for the design of buildings, other civil engineering works and construction products. The design standards embodied in these Eurocodes will be used for all European public works and are set to become the de-facto standard for the private sector in Europe, with probable adoption in many other countries.
This classic manual on structural steelwork design was first published in 1955, since when it has sold many tens of thousands of copies worldwide. For the seventh edition of the Steel Designers' Manual all chapters have been comprehensively reviewed, revised to ensure they reflect current approaches and best practice, and brought in to compliance with EN 1993: Design of Steel Structures (the so-called Eurocode 3).
