［摘要］建立了高层悬挂建筑结构减振体系的简化计算模型和运动方程，进行了频域内的参数优化和位移时程分析与计算。经过参数优化的悬挂建筑结构具有良好的减振避震性能。提出了能同时对悬挂建筑主、次结构的动力响应进行多目标优化的参数分析方法，该方法可以使得悬挂建筑主结构的频域和时域内的位移动力响应分别比普通巨型框架结构降低24%和50%以上，同时次结构的动力响应也达到一个理想的水平。

Abstract:The simplified calculation model and movement equation for high-rise suspended building structure are represented. The dynamic parameters in frequency domain are optimized and the displacement time-history is calculated and analyzed. The results show that the novel suspended building structure with optimized parameters has good dynamic performances. Moreover, a reasonable multi-objective optimization method is proposed, which can simultaneously optimize the dynamic responses of both the main structure and the substructures for the suspended building. Using this method, the displacement responses of the main structur

e calculated in both frequency domain and time domain decrease over 24% and 50% than that of the ordinary mega-frame structure respectively. Besides, the dynamic responses of substructures can also be controlled at an ideal level.

Keywords:suspended building structure; shock-absorption system; seismic response; parameter optimization; time-history analysis
