摘要
将几种地震动功率谱输入模型换算成和目标反应谱相对应的地震动输入,并应用于单自由度体系分析。结果表明,使用孙景江/江近仁迭代法将目标反应谱换算得到的等价功率谱输入精度较高,建议可以在功率谱分析方法中使用。
Several seismic input models of power spectrum corresponding to the target response spectrum are studied and used to frequency response analysis of single-degree-of-freedom system.The results are shown that PSD achieved from Sun/Jiang iteration approach can get the best result and it is worth to be recommended.
