摘要 等延性强度需求谱常用于结构需求曲线的建立.分析了等延性强度需求谱和等强度延性需求谱在概念上和计算方面的区别,表明改进能力谱法中由等延性强度需求谱反求结构的延性需求会不可避免地带来误差,建议直接采用等强度延性需求谱来计算结构的延性系数.算例分析表明,该法可以简单、有效地估计出结构在地震作用下的顶点位移需求,从而为结构的抗震性能评估提供依据. Constant-ductility strength demand spectrum is often applied to the construction of structural demand curve. The difference in the conception and calculation of constant-ductility strength demand spectrum and constant-strength ductility demand spectrum was analyzed. In the improved capacity spectrum method, the ductility demands were derived with the statistical results of constant-ductility strength spectrum, which would inevitalby cause errors. A constant-strength ductility demand spectrum was proposed to calculate the ductility factor. Analytical results indicated that the roof displacement demands of the structure under earthquake excitation, which is the basis for the evaluation of structural seismic performance, could be estimated simply and effectively with the constant -strength ductility demand spectrum.
