Re: Wind Load in the Philippines

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Calculation of wind loads in the Philippines follows the UBC format.
P = CeCqQsI
where :
P = Design wind pressure
Ce = Combined height, exposure & gust factor coeff
Cq = Pressure Coeff for the structure or portion of structure
Qs = Wind stagnation pressure at a height of 10 m
I = Importance factor

Manila is in Zone II and basic wind speed is 175 km/h and Qs is 1.50 kPa..
Ce values are about 1.20 times those indicated in the UBC. You can use
Exposure C for structures near
the sea and Exposure B otherwise.
Cq values are the same as those in the UBC.
Importance factors are 1.15 and 1.00.

Warmest regards,

Roy Sharif M. Sison
