Prediction on Translation Frequency of Damping Coefficient of Soil Based on Neural Networks
Author(s): 
Pages: 6-9,14
Year: Issue:  1
Journal: JOURNAL OF UNIVERSITY OF SCIENCE AND TECHNOLOGY OF SUZHOU(ENGINEERING AND TECHNOLOGY)

Keyword:  神经网络滞后阻尼阻尼系数转换频率;
Abstract: 利用神经网络方法研究了地震波激励作用下,土层阻尼系数转换频率与各主要影响因素之间复杂的非线性关系.通过比较时域和频域的计算结果,探讨了在土层时域分析中,如何由滞后阻尼系数形成阻尼矩阵的问题.利用实际地震波的分析结果,建立了阻尼系数转换频率的BP神经网络预测模型,从而为利用滞后阻尼系数在时域中进行土层反应分析提供了依据.
