I I e Demenstrate your understanding of the factors that contribute to wind leads by explaining each of the 7 terms of the equation below (including Vs\"). In providing your response and discussing the contributing factors, reflect upon the AS/NZS 1170.2:2021 rocedures using simple practical examples from your _. group's chosen project. 2.2_ Site wind speed The site wind speeds (Vsit) defined for the 8 cardinal directions (3) at the reference height [2) above ground (see Figure 2.1) shall be calculated from E_quation 2.2: Vsit = VRMch (MacatMth) - 2-2 where regional gust wind speed, in metres per second, for average recurrence interval of R years, as given in Lemon 3 , climate change multiplier, as given in Section 3 .3 ll Md = wind directional multipliers for the 8 cardinal directions (/9) as given in 5mm- Mz,cat = terrain/height multiplier, as given in 5651191111 Ms = shielding multiplier, as given in Section 4 Mt = ' topographic multiplier, as given in 53131191111 Generally, the wind speed is determined at the average roof height (h). In some cases, this varies according to the structure. - i , Response: ' p a ' r
