On the basis of the single-dimensional random model,the spatial correlation of ground motions in two horizontal directions is analyzed in time domain and the correlation function matrix of two-dimensional horizontal random earthquake ground motion model is established according to the concept of principal axes of motions.
假定两水平方向的地震动为平稳随机过程,基于地震动主轴模型的假设,讨论了二维地震动分量的空间相关性,在单分量平稳模型的基础上给出了二维水平地震动随机模型的相关函数矩阵。
