Constant-ductility strength demand spectrum is often applied to the construction of structural demand curve.
等延性强度需求谱常用于结构需求曲线的建立。
Furthermore, probabilistic ductility demand spectrum can be utilized in seismic structural reliability analysis.
此外，随机延性需求谱还可以用于结构的抗震可靠度分析。
On another hand, the seismic performance got from inelastic demand spectrum was increasingly popular because it avoids the complicated nonlinear time history analysis.
另外，利用非弹性需求谱确定结构的目标位移是现在的发展趋势，因为它避免了繁琐的非线性时程分析。
By introducing the yielding level factor and constructing the ductility demand spectrum, the characteristic of peak values and frequency contents of ground motions are considered separately.
引入结构屈服水平系数，建立了结构的延性需求谱，使地震动的幅值特性和频谱特性可以分开考虑。
