通过对白噪声模型、金井清模型和马尔可夫过滤有色噪声模型等常用地震动模型的分析,本文提出了更全面考虑基岩及土层的过滤特性且可解决有关加速度导数方差收敛性的新型地震动模型——双重过滤自噪声模型,并研究了其建模与定参方法.分析表明,该模型具有明确的物理意义,且更符合实际,颇具实用价值,为结构抗震可靠性分析提供了一种较好的地震动模型. By analyzing the commonly used ground motion models such as the white noise model, the Jin Jingqing model, and the Markov filtering colored noise model, this paper proposes a new type of earthquake that more fully considers the filtering characteristics of bedrock and soil layers and can solve the convergence of the acceleration derivatives derivative variance. Dynamic model—double filtered self-noise model, and studied its modeling and parameterization methods. The analysis shows that the model has a clear physical meaning, and is more practical and practical, providing a structural reliability analysis A better ground motion model.
