随机荷载的结构响应与相干尺度

Structural responses to random load and coherent scale

摘要: 介绍了随机荷载作用下结构响应的统计特性，分析了随机过程相关系数和相干函数的关系，并提出用相干尺度来表征随机荷载，既考虑了结构的频率特性，又考虑了随机荷载的频率特性。

Abstract: The statistical characteristics of structural responses subjected to random load are described. The relation between correlation coefficient and coherent function is analyzed. According to these, the concept of correlation scale considering frequency characteristics of the structure and of the random load is developed to represent the characteristics of the random load.
