Abstract

Some devices which a gusty wind tunnel test requires to measurement of a lift force on a body were reported. The effect of an instantaneous drop in a reference pressure inside of the tunnel associated with a sudden change of wind speed was able to be avoided by putting a specimen between two aerodynamic balances. This measurement system is favorable to measure the wind forces of a body in three dimensional wind flows too. Using the system, it was found that gusty wind forces on a gable roof body under a two-dimensional flow and three-dimensional flow had some differences.
