本文通过对稳态反应随时间变化规律的分析和预测，将半无限大弹性地基上高层建 筑结构对多维确定性动力作用的稳态反应问题转化成了常微分方程组的边值问题。通过对某 一高层筒中筒结构的分析计算，得出了相当合理的结论：那就是当激励荷载的频率与结构系 统的自振频率很接近时，结构的反应会出现非常大的突变。 In this paper, the steady-state response of multi-dimensional deterministic dynamic response of high-rise building on semi-infinite elastic foundation is transformed into the boundary value problem of ordinary differential equations by analyzing and predicting the regularity of steady-state reaction with time. Through the analysis and calculation of the tube structure of a high-rise tube, it is reasonable to conclude that when the excitation load frequency is very close to the natural frequency of the structure system, the structure reaction will have a very large mutation.
