Published Document (PD) 6695-2 contains non-contradictory complementary information and additional guidance for use in the UK with BS EN 1993-2, BS EN 1993-1-5, BS EN 1993-1-7, BS EN 1993-1-8 and their UK National Annexes in the design of components of steel bridges. This document only covers bridges which are executed in accordance with BS EN 1090-2.
PD 6695-2 relates only to static design of steel bridges covering slenderness parameters, buckling and bending resistance of diaphragms, bridge restraints and a few other selected topics. In some circumstances it may also be appropriate to the steel elements of composite bridges but such use needs to take full account of BS EN 1994.
PD 6695-2 does not cover the detailing of components for seismic design or the design of parapets, safety fences and other ancillary items. It also does not fully cover cable-supported bridges in respect of strength and stiffness of cables, testing, etc., for which designers can refer to BS EN 1993-1-11. Guidance on fatigue and brittle fracture resistance on these can be obtained from PD 6695-1-9 and PD 6695-1-10 respectively.
