Further Analysis of Non-Gaussian Wind Pressure Peak Factor Calculation

Variation relationship among skewness, kurtosis, and peak factor based on consistent guarantee rate. (a) Positive (right) skewness, as the skewness continues to increase, the quantile shifts to the right to make the guarantee rate unchanged. (b) Negative (left) skewness, as the skewness continues to increase, the quantile shifts to the left to make the guarantee rate unchanged. (c) High kurtosis, as the kurtosis value continues to increase, the quantile shifts away from the mean value to make the guarantee rate unchanged. (d) Low kurtosis, as the kurtosis value continues to decrease, the quantile shifts close to the mean to make the guarantee rate unchanged.
