The target displacement of a structure can be predicted by capacity spectrum method, where the demand curves are often constructed by elastic-plastic response spectra.
能力谱法可以用来估计结构的目标位移，在该方法中弹塑性反应谱常用于需求曲线的建立。

As a result, some parameters of the key points have been got including the power spectrum density (PSD), the response variance, the gust response factor for load and displacement.
生成了若干关键点的功率谱密度(PSD)和响应的均方值，以及荷载风振系数、位移风振系数。

The ground surface responsespectrum of acceleration, velocity and displacement were calculated using NDFEPS-2D.
