History <strong>of</strong> Use<br />
and Development<br />
The Eurocode system<br />
was developed to<br />
harmonize <strong>the</strong> design <strong>of</strong><br />
civil <strong>eng<strong>in</strong>eer<strong>in</strong>g</strong> works<br />
(i.e., build<strong>in</strong>gs, bridges,<br />
sign supports, and<br />
towers) among <strong>the</strong> EU<br />
countries. Thus, it<br />
applies to and, upon<br />
completion, will be<br />
mandatory for all EU countries—now number<strong>in</strong>g 15—and 4 non-EU countries. More are<br />
expected to jo<strong>in</strong> from <strong>the</strong> Eastern bloc.<br />
The general features <strong>of</strong> <strong>the</strong> Eurocodes are:<br />
• “Technical rules” are harmonized across materials.<br />
• They are design codes.<br />
• They have a limit-states format.<br />
• They use partial safety factors.<br />
As written, Eurocode features:<br />
• Pr<strong>in</strong>cipal requirements that must be followed are paragraphs marked with a “P.”<br />
• Application rules <strong>in</strong>dicate optional ways to satisfy <strong>the</strong> pr<strong>in</strong>cipal requirements.<br />
• Partial factors, placed <strong>in</strong> brackets [ ], may be set by EU-member governments,<br />
because build<strong>in</strong>g safety is a government responsibility.<br />
The Eurocodes for Civil Eng<strong>in</strong>eer<strong>in</strong>g Works are numbered as follows:<br />
• Eurocode 0: Basis for Design.<br />
• Eurocode 1: Actions.<br />
• Eurocodes 2–6 and 9: Structural Design (concrete, steel, etc.).<br />
• Eurocode 7: Geotechnical Design.<br />
• Eurocode 8: Earthquake Design.
