考虑风-结构-土耦合作用时高层建筑顺风向风振响应分析

本文综合考虑了风-结构-土的耦合作用对高层建筑顺风向风振响应的影响，研究了在各种参数下高层建筑风振响应的特性。由于在风-结构-土耦合作用问题的整个体系的控制方程中，既有时域中的耦合关系，又有频域中的耦合关系，本文提出采用傅立叶变换-时频迭代法来进行求解，较好地解决了用普通的方法难以解决的问题。最后采用数值计算的方法比较了考虑风-结构-土的耦合作用和仅考虑土-结构相互作用以及刚性基础的结构位移响应及加速度响应。

Analysis of Wind-induced Vibration Response Along-wind for High-rise Building Considering Wind Structure Soil Intraction

The coupling effects of the wind-structure-soil on the along-wind for the wind-induced vibration response of high-rise building were considered. An in-depth study of the wind-induced vibration characters of the high-rise building was carried out. The Fourier transform time domain iteration method was presented to solve the problem because of the complex coupling relationship in time domain and in frequency domain. The method is very useful to solve the problem which is hard to solve by any other common method. The displacement response and the acceleration response result considering wind-structure-soil interaction and considering soil-pile-structure interaction were compared by numerical examples.
