摘要
结构的最大反应不仅与地震动加速度的幅值有关,还与地震动的频谱特性有关,在对结构的动力特性还不了解却需要进行拟动力试验时,可以利用频域方法对地震波的选取做出定性的初步判断。
The maximum response of the structure is related not only to the amplitude of ground motion acceleration,but also with the spectral characteristics of ground motion.If the dynamic characteristics of a structure is not understood but need to conduct dynamic test,a qualitiavive preliminary judgment can be made to select seismic wave using the frequency domain method.
