| Abstract: | The existing 《Building structure load code》 did not give wind load shape coeeficient of oval and saddle-shaped roof.On this issue,numerical wind tunnel method has significant advantages such as low cost,fasting,collecting more comprehensive results.Using information of CFD and the software of FLUENT,the paper had numerical simulation of average wind pressure coefficient for oval plane and saddle-shaped roof bilding.It focused the effect on the numerical simulation for wind direction.Finally it provided reference for reasonably determining the average wind pressure coefficient of oval plane and saddle-shaped roof building. |

| Keywords: | saddle-shaped roof wind direction numerical wind tunnel pressure distribution |
