Some Effects of Housing Roof Shapes on the Wind Loads

摘要

Many wind disaster reports have said that the percentage suffering of gable roof houses by strong winds was higher than that of hipped houses. In the paper it is discussed some effects of housing roof shapes on the wind loads in uniform, pulsating and turbulent flows using wind tunnel testing. Generally the wind load of gable roof shape housing is 20/100 bigger than that of a hipped roof housing. However the existence of ridge tiles reduces the difference.
