推倒分析中的关键是加载模式的选取和目标位移的求取。
The key of push-over analysis method is load pattern and target displacement.
对应每阶振型下推覆分析的目标位移采用非弹性能力谱方法来计算。
The target displacement of each mode pushover analysis can be obtained by inelastic spectrum.
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。
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.
