Aerodynamics measures of Fujian Earth Buildings´ roof in wind leading design

The world cultural heritage Fujian Earth Buildings locate in the southeastern coastal areas, suffering from severe typhoon destruction frequently. In order to prevent wind disaster of Earth Buildings, this paper suggests using aerodynamics measures of wind transportation for the purpose of "Counseling" wind pressure on the roof of Hakka Earth Buildings. Then the passive "wind-resistance design" change to the active "wind leading design". This practice is analysis on wind pressure on the roof of Hakka Earth Buildings by the numerical simulation of CFD, which set the wind leading ring-board with different height on the roof ridge of Earth Buildings. By analyzing find that wind leading ring-board can change the air flow field of Earth Buildings\´ roof and effectively reduce the wind pressure, which is caused by high speed airflow on Earth Buildings\´ roof. Research of the dissertation shows that uses of wind transportation design can simply enhance the idea of wind resistant to the structure and achieve a better result in wind resistant. It is highly expected to solve the problem caused by the wind to Earth Buildings\´ roof efficiently and economically.
