摘要：
For the larger waveform difference between simulated ground motion and measured records during unsteady spatial ground motion, it is considered that the target design spectrum in the design code can be decomposed into the measured response spectrum and the correction term between these two factors by introducing measured records. This allows the simulated result to be close to the measured records. First, an example is given to describe the method in detail, then the influences of the incoherence and wave passage effects on the result are studied. It is found that the synthesized result is similar to the measured records and satisfies the coherence, and that the influence of the incoherence effect on the result is stronger than that of the wave passage effect.
