inelastic demand meaning in English

不受价格影响的商品需求无弹性需求
非弹性需求
无弹性需求

The inelastic demand spectra are established according to the new chinese seismic design code for buildings by means of force reduction factor r and ductility factor u , thus , a simple and practical method is established for seismic damage assessment in combination with capacity spectrum method ; the structure ' s push - over curve of second earthquake is gained by cutting the curve of quasi - test reversal load pattern method , thus , the structure ' s cumulate damage level can be computed by the capacity spectrum method too ; the results of an example are compared with the facts , and the validity and simplicity of this method is approved
利用r -关系基于抗震规范弹性反应谱建立了能力谱方法中的需求谱，并将该法和能力谱方法结合，建立了一种简单实用的结构损伤评估方法；对拟静力循环往复加载曲线的截取，得到了第二次地震作用的push - over曲线，从而能够继续使用能力谱方法得到结构物的累积损伤值；通过算例阐述了该法的计算步骤，所得结果符合基本规律，且具有概念明确、简单实用的优点。
