| Abstract: | In this paper, two horizontal components of ground acceleration are consid-ered to be stationary random process. The spatial correlation of ground motionin two horizontal directions is analysised. It discusses the function form ofself-power and cross-power spectrum of ground acceleration in two horizontaldirctions. |

| Keywords: | multi-dimensional ground motions spatial correlation self-power spectrum cross-power spectrum |
