EN 1993-3 is the third part of seven 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 buildings.
EN 1993 -3 gives design rules in supplement to the generic rules in EN 1993-1.
EN 1993-3 is intended to be used with Eurocodes EN 1990 - Basis of design, EN 1991 - Actions on structures and the parts I of EN 1992 to EN 1998 when steel structures or steel components for buildings are referred to.
Matters that are already covered in those documents are not repeated.
EN 1993 -3 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
This Part 3 of EN 1993 gives a general basis for the structural design of steel buildings, steel parts of composite buildings or buildings that are mainly of other construction materials and also steel temporary works in buildings. It gives provisions that supplement, modifY or supersede the equivalent provisions given in the various parts of EN 1993-1.
This Part 3 also gives detailed application rules that are mainly applicable to commonly used types of buildings. Where the applicability of these rules is limited, for practical reason or due to simplifications, their use and any limits of applicability are explained in the text.
Provisions for the structural fire design, the design of cold formed thin gauge members and sheeting, the design with stainless steels and with tensile elements are included in EN 1993-1 and therefore not dealt with in this part.
Provisions for composite components are covered in EN 1994-1.
The design of steel bearing piles and steel sheet pile walls is covered in EN 1993-5.
Provisions for the design of crane supporting structures are included in EN 1993-6.
This standard is concerned only with provisions for resistance, serviceability and durability of bridge structures. Other aspects of design are not considered.
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 on site needed to comply with the assumptions of the design rules.
For the execution of steel buildings, reference should be made to EN xxx'.
EN 1993-3 does not cover the special requirements of seismic design. Reference shall be made to the requirements given in EN 1998, which complements and modifies the rules of EN 1993-3 specifically for this purpose.
The following subjects are dealt with in EN 1993 -3:
Section 1: Introduction
Section 2: Basis of design
Section 3: Materials
Section 4: Durability
Section 5: Structural analysis
Section 6: Ultimate limit states
Section 7: Serviceability limit states
Section 8: Connections
Section I to 2 provide additional clauses to those given in EN 1990 "Basis of structural design".
Section 3 deals with material properties of products used in building design.
Section 4 gives general rules for durability.
Section 5 refers to the structural analysis of building structures.
Section 6 gives detailed rules for the design of cross sections and members.
Section 7 gives rules for serviceability.
Section 8 refers to connections used in building.
