主要使用纽马克—霍尔(Newmark-Hall)型反应谱研究记录的中等深度弗朗恰地震的强地震动频谱特征。数据库包含了10个弗朗恰地震的700多条水平分量记录。首先评估分量之间的变化性及各个参数(地震震级、峰值地动加速度、土层类别、台站位置和仪器类型)的相应影响。随后,研究了频谱加速度和峰值地震动参数(加速度、速度和位移)之间的相关性。分析结果表明震级对结果有重要影响,土层类别对结果有显著影响。通过使用方差分析(ANOVA)方法验证了这些发现。计算的纽马克—霍尔型频谱的响应放大因子类似于其他文献的研究结果。最后,查验了诸如纽马克—霍尔型频谱的T_B,T_E和T_F三个控制周期,获得了与罗马尼亚抗震设计规范P100-1或《欧洲规范8》略有不同的结果。
The spectral characteristics of strong ground motion of moderate-depth Frantzian earthquakes recorded primarily using the Newmark-Hall response spectroscopy were studied. The database contains over 700 horizontal component records of the 10 Frantzian earthquakes. First assess the variability between components and the corresponding effects of various parameters (magnitude of earthquake, peak ground acceleration, soil classification, station location, and instrument type). Subsequently, the correlation between spectral acceleration and peak ground motion parameters (acceleration, velocity and displacement) was studied. The analysis results show that the magnitude of the earthquake has an important impact on the results, soil types have a significant impact on the results. These findings were validated using the analysis of variance (ANOVA) method. The calculated response magnification factor for the Newmarket-Hall spectrum is similar to that of other literature. Finally, three control cycles, T_B, T_E and T_F, such as the Newark-Holl spectrum, were verified, with slightly different results than the Romanian Seismic Design Code P100-1 or Eurocode 8.
