A GENERATION METHOD OF SIMULATED EARTHQUAKE GROUND MOTION CONSIDERING PHASE DIFFERENCE CHARACTERISTICS
A method of simulating earthquake ground motions for testing the structural design of a building is proposed. In this method, a seismic wave is synthesized by combining the Fourier amplitude prescribed by the ω2 model with the Fourier phase from observation records selected on the basis of the standard deviation of the phase differences, which reflects the source and propagation characteristics of an earthquake. The proposed method can simulate seismic waves for different types of earthquakes. The dynamic behavior of a high-rise building subjected to earthquake ground motions having a long-period component was found to differ from that of a building subjected to a crustal earthquake in the vicinity of a construction site. This finding suggests the importance of considering the earthquake environment around construction sites and using simulated earthquake ground motions to test the structural designs of buildings.
