Part 2: Code of practice for wind loads

This Part of this British Standard has been prepared by Subcommittee B/525/1, Actions (loadings) and basis of design, and supersedes BS 6399-2:1995. This Part of BS 6399 is only applicable to sites in the UK. The climate dependent factors (for altitude, direction, season and probability) have been calibrated specifically for the UK. While the general methodology and pressure coefficients given in this standard may be used in other wind climates, it is essential to ensure that the reference wind data are consistent with the assumptions in this standard. The value of the site wind speed Vs should be obtained from the relevant meteorological authority | BS 6399-2 1997 BRITISH STANDARD Loading for buildings Part 2 Code of practice for wind loads ICS 91.080.01 NO COPYING WITHOUT BSI PERMISSION EXCEPT AS PERMITTED BY COPYRIGHT LAW BS 6399-2 1997 Committees responsible for this British Standard The preparation of this British Standard was entrusted by Technical Committee B 525 Buildings and civil engineering structures to Subcommittee B 525 1 Actions loadings and basis of design upon which the following bodies were represented British Constructional Steelwork Association Ltd.
