Abstract |
In the previous study, when wind direction was fixed to 0 degree, vertical mean wind pressure distributions with respect to building height had been examined by using wind tunnel test and an empirical equation of vertical mean wind pressure distribution with height had been proposed. This study examines how to change the vertical distribution of mean wind pressure of tall buildings when wind direction was changed. And the differences of vertical wind pressure distribution between to fix wind direction and to change wind direction were pointed out. Wind pressure tests were performed by using five rigid rectangular models with different cross sections in boundary layer flow. Aspect ratio of rectangular models has been fixed to six and wind direction has been changed an interval of 15 degree. |
