A study on Characteristics of Seismic Wave Observed in Yamaguchi Prefecture

In recent years, large earthquakes such as Tottoriken seibu earthquake and Geiyo earthquake occurred in Chugoku area. The characteristics of seismic wave are different in every area. In order to carry out the rational seismic design of structures, it is necessary to clarify the characteristics of seismic wave in each area. This paper aims to clarify the characteristics of the seismic wave in Yamaguchi Prefecture using the acceleration response spectrum. From the results of this investigation, simulated seismic wave was made. From the comparison of earthquake response analysis of the bridge using simulated wave and standard wave, the necessity of the setting of the seismic wave considering regional characteristics was shown.
