谱位移 meaning in Chinese

ectral di lacement
spectral displacement
spectral shift

The vulnerability evaluation procedure of hazus99 which is widely adopted in the united states and world wide is introduced in briefly . then the general technical frame of the first part is illuminated as follows : by means of the form of hazus99 , the earthquake action is expressed by demand spectra and the capacity of buildings is described by capacity curve
在此基础上，本文叙述了“吸收hazus99的表达形式，以需求谱来表达地震作用、抗力曲线表达结构的抗震能力，用需求谱和抗力曲线的交点确定的谱位移和各个震害等级对应的谱位移均值和标准差一起，分别计算建筑物对应各个震害等级的超越概率，获得易损性曲线”的一套完整的技术思路。
The probability of being or exceeding a given damage state of buildings by a given ground motion intensity is calculated from the spectral displacement corresponding to the intersecting point of the demand spectrum and the capacity curve , the median value of spectral displacement at which the building reaches the threshold of the damage state and the standard deviation of natural logarithm of spectral displacement of the damage state
文中，讨论了非弹性需求谱的推算，将现行抗震设计规范中规定的反应谱换算得到的弹性需求按对应的谱位移折减，得到非弹性需求谱。依对应的谱位移在四个需求谱上的四个点和原点，构造了典型建筑物的抗力曲线。
