This study was made for investigating the mechanism of the onset of the aerodynamic excitation of suspended roof models mainly in a wind tunnel. It was observed in the experiment that the separated shear layer on stationary models rolled up in very faint vortices, and that the shear layer was greatly excited by the model motion in a range of wind speed centered around the onset wind speed of the excitation. Therefore, it can be concluded that the role for the occurrence of the excitation of models is played by ,the vortices that are formed originally on stationary models. and are greatly amplified by the model motion as the inverse of the obtained reduced frequency of vortex shedding equaled to the reduced onset wind speed.
