| Abstract: | This paper adopted RNG k-turbulence model and used FLOTRAN CFD to simulate wind pressure distribution on the surface of single-layer double-slope-roof buildings with 12 kind of roof-angles.These buildings suffer from 3 different wind directions.The rule of wind pressure distribution,the location of dangerous areas,and the influence on wind pressure distributions from gradient change have been gained. |

| Keywords: | numerical simulation wind pressure distribution double-slope-roof houses dangerous area |
