摘　　要：阐述了通过力的折减系数R和延性系数μ建立弹塑性反应谱的原理,并由新《建筑抗震设计规范》（GB50011-2001）的加速度反应谱建立了弹塑性需求谱,为结合新抗震规范应用能力谱方法进行结构弹塑性分析奠定了基础。同时本文比较了不同的R-μ关系对需求谱的影响。The principles of establishing the inelastic spectrum by means of force reduction factor R and ductility factor μ are elaborated. The inelastic demand spectra are established according to the new Chinese Seismic Design Code for Buildings, and this lays the groundwork for structural inelastic analysis by applying capacity spectra method on the basis of new seismic design code. The influences on demand spectra by different R -μ relationships are also compared in this paper.
