11、MENT0 Introduction When there is a need for guidance on a subject that is not covered by a European Standard, a country can choose to publish documents that contain non-contradictory complementary information that supports the European Standard. Where BS EN 1337 (all parts) refers to Eurocodes, the
12、Eurocodes (BS EN 1990 to BS EN 1999 inclusive) once published are deemed to include their UK National Annexes. Eurocodes apply to design, not to assessment. Where bearings are required to be replaced on an existing highway structure, their capacity may, with the agreement of the overseeing organizat
13、ion, be chosen to accommodate the assessment loading based on UK assessment standard BD 21, The assessment of highway bridges and structures 1, with appropriate partial factors of safety for loading. Attention is drawn to the requirements in BS EN 1337 (all parts) of CE marking under the Constructio
14、n Products Directive 2 enabling bearings to be legally placed on the market in any EU Member State. The requirements of BS EN 1337 (all parts) are augmented by BS EN 1993-2:2006, Annex A. The requirements of BS EN 1337-10 are to be implemented in accordance with the Highways Agencys Inspection manua
15、l for highway structures 3.1 Scope This Published Document contains non-contradictory complementary information and additional guidance for use in the UK with BS EN 1337 (all parts). It covers the design, testing and installation of structural bearings. In addition to those bearings covered by BS EN
16、 1337, this Published Document gives guidance on knuckle and leaf bearings and composite roller bearings. NOTE Annex A gives a typical bearing schedule, which has been extended from that given in BS EN 1337-1:2000, B.1, to cover UK practice.2 Normative references The following referenced documents a
