Abstract
An input model properly representing mutually correlated earthquake ground motions is inevitably required in dynamic analysis of large scale line-like or network-like structures such as suspension bridges and buried pipelines. In this context, this paper investigated a simulation method of spatially as well as temporally variative earthquake ground motions by utilizing an autoregressive model where the properties of the actual propagating ground motions were taken into consideration in the model representation. The simulation method was justified by showing the consistency of the properties of simulated waves to the prescribed ones.Keywords
