SEISMIC RISK ANALYSIS OF URBAN REGIONS
|
抄録（英）：
Seismic risk of an urban region is defined as probability of damage, which is a function of seismic hazard and vulnerability. Seismic hazard is presented in the form of probabilistic response spectra for three types of soils, using published attenuation regressions and extreme-value type seismicity relations. Vulnerability, in terms of Damage Ratio, is correlated with spectral attenuations, for urban Japan Using this and the seismic hazard, probabilities of Damage Ratio are readily obtained. Application is made to the Osaka region, for which probabilistic response spectra are obtained, which check with available results. Seismic risk is then expressed for Osaka in terms of probabilities of Damage Ratio, for three types of soils. This is of use in design, microzonation, planning, insurance, etc.
