Popis: With regard to studies conducted using aeroelastic models with the torsional degree of freedom, self-excited vortex-induced vibration and torsional flutter occur during torsional vibrations in the case of a structure with a side ratio D / B ( D : depth, B : breadth) of 2 or more. These results suggested the necessity of investigating aerodynamic instability during torsional vibrations. The authors have been carrying out a detailed investigation by wind tunnel tests using 6-mass-point aeroelastic models into the effects of density ratio, structural damping and eccentricity in the across-wind and torsional response characteristics of a high-rise building with a side ratio of 2 (Katagiri et al., Paper for Ninth International Conference on Wind Engineering, 1995, pp. 1408–1419). In this study, the effects of the side ratio on wind response characteristics are investigated.
