摘要
为了分析风速谱的随机特性对结构风振反应的影响,应用ANSYS中的风-结构耦合分析方法,分别计算了考虑及不考虑风速随机噪声情况下生成的时程;对同一个高层建筑物的动力反应进行了时程分析;对2种情况下建筑结构表面风压及建筑结构动力反应进行了比较．比较结果表明,在考虑风速随机噪声的情况下,结构的动力反应比不考虑风速随机噪声时有一定程度的增大．
In order to observe the influence of the random noise of wind velocity, by using a real high-rise building example of wind-structure interaction analysis based on ANSYS, the dynamic response of the highrise building under the artificial time history of wind velocity is simulated according to power spectra with and without random components and. The comparison of the analytical results shows that the dynamic response of the high-rise building has been enlarged to certain degree if the random components of the input power spectra of wind are considered.
