Variability of time independent wind load components Botha, Jacques; Retief, Johan V.; Viljoen, Celeste

Abstract

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.
