摘要：

Rural house classified as a low-rise non-engineered building and it is vulnerable to damages during a windstorm event. Many studies have proven that the roof of a low-rise house is especially susceptible to damage and this phenomenon worsens for the case of rural house. This paper aims to investigate the change in distribution of pressure coefficient and streamlines pattern surrounding an isolated rural house by varying the wind directions. The analysis was conducted using Computational Fluid Dynamics method embedded in ANSYS FLUENT software package. The results showed that in most cases, the roof ridge exhibited the highest suction. The maximum suction was observed for Model A2 (30 degrees from the normal to the major face of the kitchen house).
