Abstract

In this paper, numerical simulation method was applied to study the wind-induced pressure distribution on the roofs of low-rise gable roofed buildings. First, the numerical simulation was performed based on Fluent 14.5 software platform, and the results were compared with wind tunnel test results to validate the accuracy and feasibility of numerical simulation. Then the mean wind pressure distribution characteristics and variation laws of the partial roofs of low-rise gable roofed buildings with different roof pitches were analyzed. Finally, the wind pressure distribution characteristics of low-rise gable roofed buildings surface were analyzed and summarized. The wind pressure distribution has obvious positive and negative pressure areas. The windward sides are mainly affected by positive pressure, and the negative pressure area is very small. On the contrary, the negative pressure effect on leeward sides is obvious. And higher negative wind pressure can appear at some partial areas, such as eaves, ridges and gable top edges, etc.
