摘要：

The wind pressure distribution on four types of typical gable roofs of low-rise building models are studied with pressure measurement wind tunnel tests. Three aspects are respectively discussed: the distribution characteristics of mean and fluctuating wind pressure coefficient on four types of gable roofs and eaves at different wind angles, the influence of turbulence intensity on the fluctuating wind pressure distribution and the influence of different roof types on the wind pressure spatial distribution. A detailed analysis of the experimental results show that absolute values of mean wind pressure coefficients are larger at roof ridge and near the edge of roof than on internal areas of roof. Fluctuating wind pressure coefficients increase with the turbulence intensities, which are larger on upwind roof than those on leeward roof. Generally, there are larger fluctuating wind pressure coefficients near the windward eaves. The changes of eave shapes only have more obvious influences on local wind pressure coefficients than those on overall wind pressure coefficients. These conclusions provide reference for modifying clauses about wind loads on low-rise buildings.
