摘要：
The damping elements of the bi-directional supporting TMD generate deflection angles relative to the principal axis of the structure in the planar motion. Hence, the equations of motion of the bi-directional supporting TMD system considering damper deflection angle were established. Parametric analysis of the bi-directional supporting TMD considering damper deflection angle was conducted.Base on H∞ criteria and non-dominated sorting genetic algorithm, a numerical optimization was carried out for obtaining the optimal parameters of the bi-directional supporting TMD. A high-rise landscape tower was taken as an engineering example to investigate the influence of the damper deflection angle. The results reveal that ignoring the deflection angle of the TMD damper will overestimate the vibration control effect of the bi-directional supporting TMD. The optimized bi-directional supporting TMD can provide more equivalent damping, where the attenuation rate of structural displacement response reduced by 1.46% and the ultimate dissipation of damping energy rise 7.83%. Further, the bi-directional supporting TMD perform better energy dissipation capacity by decreasing the peak value of damping force and increasing the stroke of TMD. © 2022, The Editorial Board of Journal of Basic Science and Engineering.
