000011766 520__ $$2eng$$aMany methods for synthesize near-field ground motions have been presented so far, those can be generally divided into deterministic and stochastic approaches. In general, ground motion at low frequency range is calculated by finite element or difference method, and that at high frequency is generated by stochastic synthesis separately. The ground motion at a site then is worked out by superposition of those two motions in time domain after high and low-pass filtering. The matching filter is overviewed firstly in this paper. Generally, the motion result of deterministic calculation is displacement time history while that of stochastic synthesis is acceleration. The sequence of filtering, integration or differentiate, and superposition of the two motions is deal with afterwards from two cases.
