Execut ive Summary - Sit e Specific Analysis
The design analysis of the building has not been considered for each of the 4 orthogonal directions.
Hence the maximum wind speed in any of the 8 cardinal directions has been used as the design wind
speed. This is a conservative approach.
Each cardinal direction has been considered and the results are summarised below
F ac t o r N NE E SE S SW W NW
Wind Region B
Importance level (IL) 2
Regional Wind Speed (Vr) 57.0
Terrain Category (TC) 2.86 2.88 2.83 2.98 2.99 2.87 2.7 2.94
Terrain Category Multiplier (Mz) 0.84 0.84 0.85 0.83 0.83 0.84 0.86 0.84
Shielding Multiplier (Ms) 1 1 1 1 1 1 1 1
Topographic Multiplier (Mt) 1 1 1 1 1 1 1 1
Wind Direction Multiplier 1 (Md1) 0.95 0.95 0.95 0.95 0.95 0.95 0.95 0.95
Site specific design wind speed (Vsite1) 45.7 45.6 45.8 45 45 45.6 46.5 45.3
Wind Direction Multiplier 2 (Md2) 1 1 1 1 1 1 1 1
Site specific design wind speed (Vsite2) 48.1 48 48.2 47.4 47.4 48 48.9 47.6
Design Wind Speed for the resultant forces and overturning moments on the complete
46.5 m/s
(Vsite1) building and wind actions on major structural elements.
Design Wind Speed for all other cases, including cladding and immediate supporting
48.9 m/s
(Vsite2) members (Purlins and Girts)
Snow Load Nil
Seismic Factor Nil
Durability Alert No
