EN 1993-2 is the second part of six parts of EN 1993 – Design of Steel Structures – and describes the principles and application rules for the safety and serviceability and durability of steel structures for bridges.
EN 1993-2 gives design rules which are supplementary to the generic rules in EN 1993-1-1.
EN 1993-2 is intended to be used with Eurocodes EN 1990 – Basis of design, EN 1991 – Actions on structures and the parts 2 of EN 1992 to EN 1998 when steel structures or steel components for bridges are referred to.
Matters that are already covered in those documents are not repeated.
EN 1993-2 is intended for use by
– committees drafting design related product, testing and execution standards,
– clients (e.g. for the formulation of their specific requirements),
– designers and constructors,
– relevant authorities.
(1) EN 1993-2 provides a general basis for the structural design of steel bridges and steel parts of composite bridges. It gives provisions that supplement, modify or supersede the equivalent provisions given in the various parts of EN 1993-1.
(2) The design criteria for composite bridges are covered in EN 1994-2.
(3) The design of high strength cables and related parts are included in EN 1993-1-11.
(4) This European Standard is concerned only with the resistance, serviceability and durability of bridge structures. Other aspects of design are not considered.
(5) For the execution of steel bridge structures, EN 1090 should be taken into account.
(6) Execution is covered to the extent that is necessary to indicate the quality of the construction materials and products that should be used and the standard of workmanship needed to comply with the assumptions of the design rules.
(7) Special requirements of seismic design are not covered. Reference should be made to the requirements given in EN 1998, which complements and modifies the rules of EN 1993-2 specifically for this purpose.
