This paper investigates the variability of the primary time independent components of the
design wind load formulation. It is shown that the variability of these components has a significant
influence on the total reliability of wind loads. The use of comparative studies of international wind load
standards as an indicator of the variability of the time independent wind load components is discussed. A
two part comparative study is done to determine the variability. It is found that the existing representative
probability model of wind load components underestimates even a lower limit estimate of the variability
of these components, particularly for pressure coefficients. Furthermore, insight is gained into the effects
of various structural and wind load parameters on the total variability of wind loads.Non UBCUnreviewedThis collection contains the proceedings of ICASP12, the 12th International Conference on Applications of Statistics and Probability in Civil Engineering held in Vancouver, Canada on July 12-15, 2015.
