(1) EN 1991-1-1 gives rules on the following aspects related to actions, which are relevant to the structural design of buildings and civil engineering works including some geotechnical aspects:
-   specific weight of construction materials and stored materials;
-   self-weight of construction works;
-   imposed loads for buildings.
(2) Mean values for specific weight of specific construction materials, additional materials for bridges, stored materials and products are given. In addition, for specific materials and products the angle of repose is provided.
(3) Methods for the assessment of the characteristic values of self-weight of construction works are given.
(4) Characteristic values of imposed loads are given for the following areas in buildings according to the category of use:
-   residential, social, commercial and administration areas;
-   areas for archive, storage and industrial activities;
-   garage and vehicle traffic areas (excluding bridges);
-   roofs;
-   stairs and landings;
-   terraces and balconies.
NOTE   The loads on traffic areas given in this standard refer to vehicles up to a gross vehicle weight of 160 kN. Further information can be obtained from EN 1991-2.
(5) Characteristic values of horizontal imposed loads on parapets and partition walls acting as barriers are provided.
NOTE   Forces due to vehicle impact are specified in EN 1991-1-7 and EN 1991-2.
1.2   Assumptions
(1) The general assumptions of EN 1990 apply.
(2) EN 1991-1-1 is intended to be used with EN 1990, the other parts of EN 1991 and the other Eurocode parts for the design of structures.

European foreword
This document (prEN 1991-1-1:2023) has been prepared by Technical Committee CEN/TC 250
“Structural Eurocodes”, the secretariat of which is held by BSI.
CEN/TC 250 is responsible for all Structural Eurocodes and has been assigned responsibility for
structural and geotechnical design matters by CEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1991-1-1:2002.
The first generation of EN Eurocodes was published between 2002 and 2007. This document forms part
of the second generation of the Eurocodes, which have been prepared under Mandate M/515 issued to
CEN by the European Commission and the European Free Trade Association.
The Eurocodes have been drafted to be used in conjunction with relevant execution, material, product
and test standards, and to identify requirements for execution, materials, products and testing that are
relied upon by the Eurocodes.
The Eurocodes recognize the responsibility of each Member State and have safeguarded their right to
determine values related to regulatory safety matters at national level through the use of National
Annexes.
prEN 1991-1-1:2023 (E)
Introduction
0.1 Introduction to the Eurocodes
The Structural Eurocodes comprise the following standards generally consisting of a number of Parts:
— EN 1990 Eurocode: Basis of structural and geotechnical design
— EN 1991 Eurocode 1: Actions on structures
— EN 1992 Eurocode 2: Design of concrete structures
— EN 1993 Eurocode 3: Design of steel structures
— EN 1994 Eurocode 4: Design of composite steel and concrete structures
— EN 1995 Eurocode 5: Design of timber structures
— EN 1996 Eurocode 6: Design of masonry structures
— EN 1997 Eurocode 7: Geotechnical design
— EN 1998 Eurocode 8: Design of structures for earthquake resistance
— EN 1999 Eurocode 9: Design of aluminium structures
— New parts are under development, e.g. Eurocode for design of structural glass
The Eurocodes are intended for use by designers, clients, manufacturers, constructors, relevant
authorities (in exercising their duties in accordance with national or international regulations),
educators, software developers, and committees drafting standards for related product, testing and
execution standards.
NOTE Some aspects of design are most appropriately specified by relevant authorities or, where not specified,
can be agreed on a project-specific basis between relevant parties such as designers and clients. The Eurocodes
identify such aspects making explicit reference to relevant authorities and relevant parties.
0.2 Introduction to EN 1991 (all parts)
(1) EN 1991 specifies actions for the structural and geotechnical design of buildings, bridges and other
civil engineering works, or parts thereof, including temporary structures, in conjunction with EN 1990
and the other Eurocodes.
(2) EN 1991 does not cover the specific requirements of actions for seismic design. Provisions related to
such requirements are given in EN 1998 (all parts), which complement and are consistent with EN 1991.
(3) EN 1991 is also applicable to existing structures for:
— structural assessment,
— strengthe
