4.1.7.2. — Dynamic Effects of Wind
(1) Buildings whose height is greater than 4 times their minimum effective width, which is defined in Sentence (2), or greater than 120 m and other buildings whose light weight, low frequency and low damping properties make them susceptible to vibration shall be designed by,
(a) experimental methods for the danger of dynamic overloading, vibration and the effects of fatigue, or
(b) using a dynamic approach to the action of wind gusts.
(2) The effective width, w, of a building shall be calculated using the formula,
where,
the summations are over the height of the building for a given wind direction,
hi is the height above grade to level i, as defined in Sentence 4.1.7.1.(5), and
wi is the width normal to the wind direction at height hi,
the minimum effective width is the lowest value of the effective width considering all possible wind directions.
