1.1 Scope of prEN 1998-1-1 (1) This document is applicable to the design and verification of buildings and other structures in seismic regions. It gives general rules relevant to all types of structures, with the exception of special structures. NOTE Special structures belong to consequence class CC4, which is not fully covered by the Eurocodes. The categories of structures of consequence class CC4 where EN 1998, or parts of it, apply in a country can be provided by the relevant Authorities or can be found in the National Annex. (2) This document provides basic performance requirements and compliance criteria applicable to buildings and civil engineering works in seismic regions. (3) This document gives rules for the representation of seismic actions and the description of the design seismic situations. Certain types of structures, dealt with in other parts of EN 1998, need supplementary rules which are given in those relevant Parts. (4) This document contains general methods for structural analysis and verification under seismic actions, including base-isolated structures and structures with distributed dissipative systems. (5) This document 1 contains rules for modelling and verification of ultimate strengths and deformations. 1.2 Assumptions (1) The general assumptions of prEN 1990:2021, 1.2, are supplemented as given in (2) to (6). (2) It is assumed that no change in the structure and in the masses carried by the structure will take place during the construction phase or during the subsequent life of the structure with respect to the design unless proper justification and verification is provided. This applies to ancillary elements as well (see 3.1.2). Due to the specific nature of the seismic response, this applies even in the case of changes that lead to an increase of the structural resistance. (3) The design documents are assumed to indicate the sizes, the details and the properties of the materials of the structural members. If appropriate, the design documents are also assumed to include the properties of special devices to be used and the distances between structural and ancillary elements. The necessary quality control provisions are assumed to be specified. (4) Members of special structural importance requiring special checking during construction are assumed to be identified on the design documents. In this case, the verification methods to be used are also assumed to be specified. (5) In case of high seismic action class (4.1.1(4)), formal quality system plans, covering design, construction, and use, additional to the control procedures prescribed in the other relevant Eurocodes, are assumed to be specified.
