| Summary |
In this study, wind tunnel experiments and computational fluid dynamics (CFD) simulation were carried out to investigate the characteristics of wind loads on a cylindrical free roof. The effects of parameters such as rise/span ratio f/B , length/span ratio W/B , and wind direction o n the characteristics of wind pressures and forces acting on the cylindrical free roof and the flow around the roof were investigated. Based on the distributions of the mean wind force coefficients along two representative lines in the central and edge zones, we have proposed a model of the wind force coefficient distributions used for designing the main wind force resisting systems. Furthermore, models of positive and negative peak wind force coefficients for cladding design have been proposed.
