内容記述 | In this study, we investigated the influence of site amplification effect and source spectra on amplification of seismic intensity for the purpose of obtaining basic information for accurately evaluating the amplification of seismic intensity (dI). Firstly, an evaluation formula for dI was obtained based on the relation between earthquake motion spectrum and amplification factor of earthquake motion index. Using the obtained evaluation formula, dI for three earthquake types, various magnitudes, fmax, site amplification effects was estimated. As a result of investigating the relationship between the fundamental peak frequency of site amplification effects and dI, the frequency of maximum dI was shifted to the lower frequency range as magnitude increased for all earthquake types. In all earthquake types, dI tended to converge to a certain value as magnitude increased. | |||||
