An 8.0-m high portal frame building is proposed on an exposed site (category 2) in Melbourne, with a length of 48.0 m, a width of 20.0 m, and a roof pitch of 5°. Rafters are spaced at 6.0 m centres and span 15.0 m. Purlins and girts are spaced at 1500 mm centres. a) Determine the site wind speeds (Vsit,p) for the 8 cardinal directions. Assuming the building's orthogonal axes align with the cardinal directions, calculate the design wind speed (Vdes,e) for the North and West directions. Consider M = M₁ = M₁ = 1.0. b) Using the design wind speed for the west direction, calculate the design internal pressures for (1) the roof, (2) the windward wall face (3) the leeward wall face, and (4) the sidewall faces. Consider all walls are permeable, Kv = 1.0. c) Using the design wind speed for the west direction, calculate the design external pressure calculate the design internal pressures for (1) the roof, (2) the windward wall face (3) the leeward wall face, and (4) the sidewall faces. Consider ko = k = ko = 1.0. d) Using the determined internal and external pressures, calculate the uniformly distributed wind loads (kN/m) on the portal frame rafter and columns.

Transcribed Image Text:An 8.0-m high portal frame building is proposed on an exposed site (category 2) in
Melbourne, with a length of 48.0 m, a width of 20.0 m, and a roof pitch of 5°. Rafters are
spaced at 6.0 m centres and span 15.0 m. Purlins and girts are spaced at 1500 mm
centres.
a) Determine the site wind speeds (Vsit,p) for the 8 cardinal directions. Assuming the
building's orthogonal axes align with the cardinal directions, calculate the design
wind speed (Vdes,e) for the North and West directions. Consider M = M₁ = M₁ = 1.0.
b) Using the design wind speed for the west direction, calculate the design internal
pressures for (1) the roof, (2) the windward wall face (3) the leeward wall face, and
(4) the sidewall faces. Consider all walls are permeable, Kv = 1.0.
c) Using the design wind speed for the west direction, calculate the design external
pressure calculate the design internal pressures for (1) the roof, (2) the
windward wall face (3) the leeward wall face, and (4) the sidewall faces. Consider
ko = k = ko = 1.0.
d) Using the determined internal and external pressures, calculate the uniformly
distributed wind loads (kN/m) on the portal frame rafter and columns.
