BS CP3: CHAPTER V: PART 2 Historical [ Withdrawn ]

BS CP 3:Chapter V-2:1972 gives methods for calculating the maximum gust wind loads that should be taken into account when designing buildings or components thereof.

BS CP 3:Chapter V-2:1972 does not apply to buildings that are of unusual geometric shape, or have unusual site locations warranting special consideration, the loading for which should be obtained by experimental methods.

BS CP 3:Chapter V-2:1972 does not apply to buildings whose structural properties (weight, stiffness, frequency or damping) make them susceptible to dynamic excitation. These should be assessed using published sources, examples of which are given in Appendix J, or by experimental methods. It should be noted that if a building is susceptible to excitation by vortex-shedding or other aerodynamic instability the maximum dynamic response may occur at wind velocities lower than the maximum.

For the purposes of this Code, "experimental methods" include properly-conducted wind tunnel tests which meet the provisions given in Appendix K. These experimental methods are also recommended when wind loading data are required in more detail than is given in this Code, or when the form of the building can be changed in response to the test results in order to give an optimal design.'
