俯冲带板内地震水平与竖向加速度反应谱比研究
Study on horizontal and vertical response spectral ratio for earthquakes from subduction slab
摘要
Abstract
The horizontal-to-vertical spectral ratio(HVSR)model is employed to adjust the design response spectral ratio under non-specific earthquake scenario—earthquakes lacking moment magnitude and seismic distance information,and it can provide a theoretical basis and technical support for the calculation of vertical response spectra from known horizontally oriented response spectra.In the study,raw data from the K-NET and KiK-net networks in Japan were collected and processed to obtain 4 695 strong earthquakes within the subduction zone plate,and the HVSR model of the subduction zone plate earthquakes was established by taking into account only the effects of spectral period and site conditions,which can be used for the HVSR calculations of the non-specific earthquake scenario under the condition of 5%damping ratio.The results indicate that the earthquake type and site classes have significant effects on the HVSR.The peak period of the site effect coefficients coincides with the mean site period,showing a significant site resonance effect.The predicted values of the HVSR under the non-specific earthquake scenario are larger than the recommended values in the current earthquake-resistant design codes,and the dispersion caused by the source effect is smaller than that caused by the path and site effects,which results in the modeled standard deviation between events being much smaller than the within-event standard deviation.关键词
