THE CALCULATION OF WIND PRESSURE PROBABILITY FOR VARIOUS TIME SCALES IN CHINA

In this article the regular teriminal observations of 2-munite average wind velocity are converted to 10-munite ones by formulae for different regions with different values of air density and gravitational constants.The equation of wind pressure coefficient q as a function of elevation (h) obtained is q=0.0644 e-0.0001h.Nationwide charts for return period of wind pressure once in 10,20,30,60,and 100 years have been prepared for the benefit of various fields of engineering.These charts have been included in the design codes for road,railway,electric power,telecommunication and harbour engineering.
