초록
Multi-bay gable roof buildings are commonly used in a number of industries. This wind-tunnel study has been carried out to assess wind loads on one and multi-bay gable roofs of low-rise buildings. This paper compared one bay with multi bay model. The length b of the one bay model represent full-scale building was 200m and the width d of the span was 32m. The mean height of the roof h was 15.7m. One bay model is long span and low-rise building. Multi bay model with five span low-rise building of a large scale. Peak external wind pressure coefficient and cladding wind loads were measured on model with one and five bay model. The results indicate that peak external wind pressure coefficient on the roof edge and corner was increased. And the results compared with wind standard of KBC-S2005. One and multi bay model were somewhat larger than wind standard.
Abstract
Multi-bay gable roof buildings are commonly used in a number of industries. This wind-tunnel study has been carried out to assess wind loads on one and multi-bay gable roofs of low-rise buildings. This paper compared one bay with multi bay model. The length b of the one bay model represent full-scale building was 200m and the width d of the span was 32m. The mean height of the roof h was 15.7m. One bay model is long span and low-rise building. Multi bay model with five span low-rise building of a large scale. Peak external wind pressure coefficient and cladding wind loads were measured on model with one and five bay model. The results indicate that peak external wind pressure coefficient on the roof edge and corner was increased. And the results compared with wind standard of KBC-S2005. One and multi bay model were somewhat larger than wind standard.
