| 摘 要： | 为解决人造地震动拟合时出现的经幅值调整仍未收敛的问题,分析了造成相位调整效果不稳定的原因并给出有关参数的补充公式,提出由地震动各分量反应对应的相位余弦符号来实现相位分区并给出各分区的相位调整方法.针对经相位调整仍无法收敛情况,在相位调整完成后继续使用幅值调整来改善拟合效果.算例表明本方法可有效实现迭代收敛并生成较好拟合...

| Abstract: | In order to eliminate the non-convergence occurring sometimes in amplitude adjustment for synthesizing artificial ground motion,the unsatisfactory reason of phase adjustment is analyzed and the supplemental formula for relevant parameters is provided.By judging phase partition based on phase cosine symbol of ground motion component's responses,the phase adjustment method based on cosine partitions is presented.For the non-convergence of phase adjustment in some cases,the application of amplitude adjustment ... |
