摘要
指出分析双向水平地震动峰值相关性的必要性，采用常规回归方法和双随机变量一致最小二乘法统计得出五组相关关系的表达式，给出工程中使用这些相关关系时的建议。
It is necessary to study the correlation between the same peak values of two horizontal components of earthquake ground motions. The formulae for correlation of 5 peak values are regressed by using the Least Square method and the uniform LS method in which the variables are both taken to be random. Ths suggestion on the application of the formulae is given in this paper.
