THE PARAMETER INFLUENCE ANALYSIS OF SIMULATION FOR SPATIALLY VARYING GROUND MOTION

Based on the existing simulation and synthesis method of spatial correlative varying ground motion,the influences of coherence function models,phase values and variations of calculation point numbers were analyzed focally on the synthesis results of multipoint ground motion. In the meantime,the contrast analysis was carried out on time-frequency domain of multi-point ground motion under different parameter values. The analysis results showed that the above parameters had significant influences on the synthesis of multi-point ground motion,of which,the influence of the phase was the most significant In addition,improvement suggestions and recommended measures were proposed on the synthetic parameter value model of spatial-correlated multi-point ground motion.
